2. Which statement is false about the relationship of the sides in the triangle shown in the picture below?
x=3
none of these are false.
x=1
x=7
Answers
Based on the triangle inequality theorem, the that is false about the relationship of the side of the triangle given is: D. x = 7.
What is the Triangle Inequality Theorem?The triangle inequality theorem holds that the length of any side of a triangle is less than the sum of the length of the sides of the other two sides.
Applying the triangle inequality theorem, it means the following should be true for any value of x given:
x + 2 + x + 3 > 3x - 2
2x + 5 > 3x - 2
Plug in x = 3 to find out:
2(3) + 5 > 3(3) - 2
11 > 4 (True)
Plug in x = 1 to find out:
2(1) + 5 > 3(1) - 2
8 > 2 (True)
Plug in x = 7 to find out:
2(7) + 5 > 3(7) - 2
19 > 19 (FALSE)
Therefore, the false statement is: D. x = 7.

Which of the following proves ABC= DEF?
Answers
Answer: A
Step-by-step explanation:
In the diagram, we see that we have two pairs of congruent angles, so it is going to be either ASA or AAS congruence.
To determine if it is ASA or AAS congruence, we can use the fact that for ASA, the side is included between the congruent angles, whereas in AAS, the side isn't.
Since the congruent side is included between the two angles, there is ASA congruence.
What is the y-intercept of the function f(x) = -2/-9x+1/3?
Answers
Answer:
b = 1/3
Step-by-step explanation:
The general structure of equations in slope-intercept form is:
y = mx + b
In this form, "m" represents the slope and "b" represents the y-intercept.
The given equation is already in slope-intercept form. In other words, you have already been given "m" and "b". Therefore, the value which corresponds with the y-intercept is (1/3).
f(x) = mx + b
f(x) = -(2/9)x + 1/3

The value of y in the given logarithmic equation is 3. The correct option is C. 3
Evaluating Logarithmic equationFrom the question, we are to determine the value of y in the given logarithmic equation
The given equation is
[tex]log_{4}64=y[/tex]
By applying one of the laws of logarithm, we get
[tex]64 = 4^{y}[/tex]
Now, express 64 in index form,
[tex]4^{3} = 4^{y}[/tex]
Since the bases are equal, we can equal the powers to get

Identify the angle of depression.
Answers
Answer:
4
Step-by-step explanation:
An angle of elevation is the angle formed by a horizontal line and a line of sight to a point above the line.
An angle of depression is the angle formed by a horizontal line and a line of sight to a point below the line.
∠3 is an angle of elevation because it is formed by the line of sight that is above the horizontal line.
∠4 is an angle of depression because it is formed by the line of sight that is below the horizontal line.
∠5 is neither an angle of depression nor an angle of elevation because it is not formed by the horizontal line and the line of sight.
∠6 is an angle of elevation because it is formed by the line of sight that is above the horizontal line.
Therefore, the angle of depression is ∠4.

x + 112 = 180x = 68°y + 81 = 180y = 99°Answer:
9. x = 200 and y = 100
10. x = 68 and y = 99
Step-by-step explanation:
Question 9
The measure of an arc is the measure of its central angle.
⇒ x = 200
This is a non-cyclic quadrilateral as not all its vertices touch the circumference of the circle.
The angle at the center is twice the angle at the circumference.
⇒ y = 200 ÷ 2
⇒ y = 100
Question 10
This is a cyclic quadrilateral as all its vertices touch the circumference of the circle.
The opposite angles in a cyclic quadrilateral add up to 180°.
⇒ x + 112 = 180
⇒ x = 68
⇒ y + 81 = 180
⇒ y = 99

The correct transformation is a rotation of 180° around the origin followed by a translation of 3 units up and 1 unit to the left.
Which transformation is used to get A'B'C'?
To analyze this we can only follow one of the vertices of the triangle.
Let's follow A.
A starts at (3, 4). If we apply a rotation of 180° about the origin, we end up in the third quadrant in the coordinates:
(-3, -4)
Now if you look at A', you can see that the coordinates are:
A' = (-4, -1)
To go from (-3, -4) to (-4, -1), we move one unit to the left and 3 units up.
Then the complete transformation is:
A rotation of 180° around the origin, followed by a translation of 3 units up and 1 unit to the left.
