What is AC, the length of AC after the dilation? What is the measure of ZA?
A. A'C' = 5, m ZA= 12
O B. A'C' = 5, mZA'= 37°
O C. A'C' = 45, m A'= 37°
D. A'C' = 4, mZA'= 53°

Answer 1

A'C = 45, m A' = 37

Explanation:

You find the 45 by multiplying 15, the length of A'C by 3 to find the original size.
