Answer: 60 degrees

Step-by-step explanation:

add 90 50 and 100

= 240

Total of all interior angles should be 360

So 360-240=120

Straight line: 180 degrees

180-120=60

The area of shaded region = area of triangle - area of circle = 33.73 sq. m.

Area of circle = πr²

Area of triangle = 1/2(base × height)

The area of the shaded region = area of triangle - area of circle

=  1/2(14 × 12) - π × 4²

Area of shaded region = 84 - 50.27

Area of shaded region = area of triangle - area of circle = 33.73 sq. m

[tex]\tan 39 \textdegree = \displaystyle \frac{h}{89}\\\\89\tan 39 \textdegree = h\\\\h = 72[/tex]Answer:

72 m

Step-by-step explanation:

Hi there!

Using the given information, we can construct a diagram. Please see the attached image.

We need to solve for the height of the building, or the length of the side opposite the angle that measures 39°. Given the only other piece of information is the length of its adjacent side, which is 89 m, we can use the tangent ratio to solve for the height:

[tex]\tan \theta = \displaystyle \frac{opposite}{adjacent}[/tex]

Plug in the given values:

tan 39° = h/89

89 tan 39° = h

h = 72

Therefore, the height of the building is 72 m.

Answer:

y = -6x + 7

Step-by-step explanation:

Slope-intercept form: y = mx + b

where:

Given: a line with a slope of -6, and y-intercept of 7

Equation: y = -6x + 7

Randomly select x-values that will help you graph the equation:

when x = -2:

y = -6(-2) + 7 [multiply]

y = 12 + 7 [add]

y = 19

coordinate: (-2, 19)

when x = 1:

y = -6(1) + 7 [multiply]

y = -6 + 7 [add]

y = 1

coordinate: (1, 1)

when x = 2:

y = -6(2) + 7 [multiply]

y = -12 + 7 [add]

y = -5

coordinate: (2, -5)

These coordinates fall on the line for the linear equation. Graph them on a coordinate plane, and they should give you the line for the equation.

Answer:

D.) Max started at a height of 30 meters and is ascending at 10 meters per hour.

Step-by-step explanation:

This equation y = 10x + 30 can be used to represent this situation, where y is Max's elevation in meters and x is the number of hours Max has been hiking

Max started at the height of 30 meters and is ascending at a rate of 10 meters per hour. Then the correct option is A.

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Given

The equation is y = 10x + 30.

Where y is Max's elevation in meters and x is the number of hours.

Max has been hiking.

From the equation, we can conclude.

Max is ascending at a rate of 10 meters per hour.

Max is at the height of 30 meters at the starting.

Thus, option A is correct.

Answer:

  10.3 cm

Step-by-step explanation:

There are a few ways to do this.

Using the law of cosines, you have ...

  b² = a² +c² -2ac·cos(B)

  b² = 11² +11² -2(11)(11)·cos(56°) = 106.67

  b = √106.675 ≈ 10.3

  AC = 10.3 cm

__

Using trig functions. When you draw an altitude in this isosceles triangle from B to AC, it divides AC in half, and it divides angle B in half. The sine relation can help here:

  Sin = Opposite/Adjacent

  sin(56°/2) = (AC/2)/(11 cm)

  AC = (22 cm)sin(28°) ≈ 10.3 cm

__

Using a triangle solver, you can find the value of AC to be about 10.3 cm. Triangle solvers are available as apps and on the web. Your graphing calculator may have one. See attached for the results from a nice solver available on the web. Units are cm.

Answer:

i think this is the correct answer

Step-by-step explanation:

Simplifying

8x + -7y = 23

Solving

8x + -7y = 23

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '7y' to each side of the equation.

8x + -7y + 7y = 23 + 7y

Combine like terms: -7y + 7y = 0

8x + 0 = 23 + 7y

8x = 23 + 7y

Divide each side by '8'.

x = 2.875 + 0.875y

Simplifying

x = 2.875 + 0.875y

The height of the ramp is 49.45in

Data;

To solve this problem, we can use trigonometric ratio SOHCAHTOA

Since we have the value of the angle and length of the ramp, this can be illustrated as hypotenuse and angle between the hypotenuse and opposite of the right-angle triangle.

From the information above, we have angle and hypothenuse but we need to solve for the opposite of the right-angle triangle. The sine angle can solve this problem.

[tex]sin \theta = \frac{opposite}{hypothenuse} \\sin 22 = \frac{x}{132} \\x = 132 sin 22\\x = 49.45 in[/tex]
