Question

AABC is dilated by a factor of 2 to produce AA'B'C

What is A'C, the length of AC after the dilation? What is the measure of


A. A'C' = 60, mA'= 28°

B. AC = 32, m4A = 62°

C. A'C' = 15, mA' = 28°

D. A'C' = 60, mA' = 56

Answer 1

Answer: A. A'C' = 60, mA'= 28°

Step-by-step explanation:

Since the figure was dilated by a factor of 2, it means that all lengths and angles of the figure will be multiplied by a factor of 2.

Therefore, the initial length of AC was 30 and the measure of mA was 14°.

After the dilation, the length A'C' would be 60 (because 30*2 = 60) and the measure of mA' would be 28° (because 14*2 = 28°).
