Task 1:a) The measure of angle  Y'Z'X'= 22  degrees

Task2:b) The measure of angle X'Y'Z'= 75 degrees.

An angle is a figure in Euclidean geometry made up of two rays that share a terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are located in the plane where the rays are located. The meeting of two planes can also create an angle. Angle can also be used to describe the size of an angle or of a rotation. This metric represents the proportion of a circular arc's length to radius.

Angle Y'Z'X' = YZX = 22 degrees (in a triangle, angle dilation does not

modify angle size). Only the sides' length varies.

The sum of the triangle's angles for the XYZ angle is 180 - 83

-22 = 75 degrees. Since there are already two angles supplied, the third

angle is 75 degrees, so X'Y'Z' = XYZ = 75 degrees. The dilation angle size remains unchanged (for the same reason as in the previous challenge).

To determine the point and slope from the given equation, we can rewrite the equation in the standard form of a linear equation: y = mx + b, where m is the slope and b is the y-intercept (the point at which the line crosses the y-axis).

In this case, the equation is already in the standard form, so we can immediately see that the slope is -5 and the y-intercept is (0, 4). This means that the point at which the line crosses the y-axis is (0, 4), and the slope of the line is -5.

Therefore, the correct answer is:

Point: (0, 4)

Slope: -5

Answer: Deep inside Earth, between the molten iron core and the thin crust at the surface, there is a solid body of rock called the mantle. When rock from the mantle melts, moves to the surface through the crust, and releases pent-up gases, volcanoes erupt. Extremely high temperatures and pressure cause the rock to melt and become liquid rock or magma. When a large body of magma has formed, it rises through the denser rock layers toward Earth's surface.  Magma that has reached the surface is called lava.

You are running the concession stand for the basketball game. You sell hot dogs for $1.50 and drinks for $2.

a)  an equation in a standard form that models this situation is

1.5H + 2D = 250

b) Hot dogs sold 104

Generally, a) Let H be the number of hot dogs sold and D be the number of drinks sold. The equation that models this situation is:

1.5H + 2D = 250

b) To find the number of hot dogs sold, we can solve the equation for H:

1.5H = 250 - 2D H = (250 - 2D) / 1.5

Substituting D = 47 into this equation gives us:

H = (250 - 2*47) / 1.5 H = (250 - 94) / 1.5 H = 156 / 1.5 H = 104

The height of the candy cane is 11.4024 feet when the man is looking at the top of the candy cane at an angle of 35°.

We have the following information:

A 3 foot Gingerbread man is standing 12 feet from the base of the tall candy cane he has ever seen. He is looking at the top of the candy cane at an angle of 35⁰.

Now, we can find the height of the candy cane using the trigonometric function of tan.

Now, the base will be 12 feet and the height of the candy cane will be added to 3 feet to find the real height of the cane.

Tan 35 = height of the cane/base

0.7002 = Height of the cane/12

Height of the cane = 12*0.7002

Height of the cane = 8.4024 feet

Real height of the cane = 3+8.4024 feet

Real height = 11.4024 feet

Hence, the candy cane is 11.4024 feet when the man is looking at the top of the candy cane at an angle of 35°.

In vertex form the equation of the parabola is [tex]y = -2(x+2)^{2} -5[/tex].

What is Vertex form if Parabola ?

When a graph crosses its symmetry axes, the vertex formula in mathematics may be used to get the vertex coordinate of a parabola. The vertex point is often represented by (h, k). We are aware that a parabola's conventional equation is y=ax2+bx+c. The vertex in this case should be near the base of the U-shaped curve if the coefficient of x2 is positive. The vertex should be at the peak of the U-shaped curve if the coefficient of x2 is negative. The standard form and vertex form of a parabola, as well as the vertex formula, will be covered in this article.

We are aware that the parabola's conventional form is y=ax2+bx+c.

So, y = a(x-h)2 + k is the vertex form of a parabola.

To determine a parabola's vertex, use the vertex formula. There are two methods for locating a parabola's vertex.

Vertex, (h, k) = (-b/2a, -D/4a)

Equation of the parabola,

y = [tex]-2x^{2} - 8x -13[/tex]

here ,

a = -2 , b = -8 and c = -13.

Therefore,

h = -b/2a = +8/-4 = -2 and,

k = -D/ 4a = [tex]-(b^{2} - 4ac)/4a[/tex] = -(64 - 104)/-8 = -40/8 = -5

So, the coordinate of vertex is (-2, -5)

So the vertex form of equation of parabola is

[tex]y = a(x-h)^{2} + k[/tex]

⇒ [tex]y = a(x+2)^{2} -5[/tex]

⇒ [tex]y = ax^{2} + 4ax +4a -5[/tex]

Equating this equation with equation pf parabola we get a = -2

So, in vertex form the equation of the parabola is [tex]y = -2(x+2)^{2} -5[/tex].

Step-by-step explanation: Common sense

Part A: A system of equations to model this situation includes:

Equation 1: x + y = 461

Equation 2: 3x + 4y = 1624.

Part B: The solutions of the equations show that 220 students bought tickets at $3 each, while 241 adults bought the tickets at $4 each to give the total sales revenue as $1,624.

A system of equations means simultaneous equations.

Simultaneous equations are two or more equations solved at the same time.

Simultaneous equations can be solved by graphing, substitution, and elimination methods.

In this situation, we decided to solve the equations by substitution after equating x = 461 - y from the first equation.

The total number of tickets sold for the school play = 461

The cost of student tickets per unit = $3

The cost of adult tickets per unit = $4

The total revenue raised = $1,624

Let the number of students = x

Let the number of adults = y

x + y = 461  ... Equation 1

3x + 4y = 1624  ... Equation 2

From Equation 1:

x = 461 - y  ... Equation 3

Substitute x in Equation 2

3(461 - y) + 4y = 1624

1,383 - 3y + 4y = 1624

y = 241

From Equation 1:

x = 461 - y

= 461 - 241

= 220

Check:

3x + 4y = 1624

3(220) + 4(241) = 1624

660 + 964 = 1624

Answer: 6 and 8

Step-by-step explanation: A right triangle is a triangle with one angle that measures 90 degrees. The side opposite the right angle is called the hypotenuse, and the other two sides are called the legs. In this case, the hypotenuse is 10cm long.

If one angle of the triangle is 40 degrees, then the other angle must be 90-40 = 50 degrees. The remaining two angles of a triangle must add up to 180 degrees, so the third angle is 180-40-50 = 90 degrees. This means that the triangle is a right triangle, and we can use the Pythagorean theorem to find the lengths of the legs.

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs. In this case, we have a2 + b2 = c2, where a and b are the lengths of the legs and c is the length of the hypotenuse.

Substituting the values from the problem, we have a2 + b2 = 102, which simplifies to a2 + b2 = 100. Since we don't know the values of a and b, we can't solve for them directly. However, we can use the fact that the angle opposite the longer leg is 50 degrees, and the angle opposite the shorter leg is 40 degrees. This means that the longer leg is the opposite side of the 50-degree angle, and the shorter leg is the opposite side of the 40-degree angle.

Since the longer leg is opposite the 50-degree angle, and the shorter leg is opposite the 40-degree angle, we can use the tangent function to find the ratio of the lengths of the legs. The tangent of an angle is defined as the ratio of the opposite side to the adjacent side, so we have tangent(50 degrees) = opposite side / adjacent side = a / b, and tangent(40 degrees) = opposite side / adjacent side = b / a.

Solving for a and b, we have a = b * tangent(50 degrees) and b = a * tangent(40 degrees). Since the legs are the opposite sides of the 40- and 50-degree angles, we can substitute the values from the problem to get a = b * tangent(50 degrees) = 100 * tangent(50 degrees) and b = a * tangent(40 degrees) = 100 * tangent(40 degrees).

To find the values of tangent(50 degrees) and tangent(40 degrees), we can use a calculator or look up the values in a table of trigonometric functions. We find that tangent(50 degrees) = 1.191753592594, and tangent(40 degrees) = 0.839099631177. Substituting these values into the equations for a and b, we have a = 100 * 1.191753592594 = 119.1753592594 and b = 100 * 0.839099631177 = 83.9099631177.

Rounding to the nearest whole number, we have a = 119 and b = 84. The lengths of the legs of the triangle are therefore 6 and 8.
