Answer:
C
Step-by-step explanation:
If you draw a straight line through all the corresponding vertices, where the three vertices meet up at is the center of dilation, they all meat up at point C so C is the center of dilation.
Let the angle = x
Using the figure below, to find x, setup the equation:
x+70+x=180
2x+70=180
2x=110
x=55°
So the ball hits the surface at 55° and bounces back at 55°.
Answer: 55°
Its to hard I don’t know sorry
