First of all, we know that a line is 180°. This means if we add the angles of 61°, 57°, and angle y, we should get 180<span>°.

Simplify:

Subtract 118° to both sides:

We also know that all three angles of a triangle add up to 180<span>°. So we have:

Simplify:

Subtract 129° to both sides:

Answer:
7
Step-by-step explanation:
Reflection is a rigid transformation, so the side length does not change.
A'B' = 7
-18 + 9 = -9
-9 = -9
If you're looking for false or true.
The answer would be true
Answer:
x = -9
Step-by-step explanation:
6 - 2/9x = 8
Subtract 6 from each side
6-6 - 2/9x = 8-6
-2/9 x = 2
Multiply each side by -9/2 to isolate x
-9/2 * -2/9x = 2*-9/2
x = -9
Answer:
transformations of function 3(-7(x+2))-4
- vertical stretch
- horizontal compression
- translates left
- translates down
- reflection across y-axis
