Answer:

A'C' = 15

The measure of angle A = 37 degrees

Explanation:

Given a dilation factor of 3, all we need to do is multiply the lengths of the sides of the triangle with 3 which is the scale factor as shown below;

[tex]\begin{gathered} AC=5 \\ A^{\prime}C^{\prime}=5\times3=15 \end{gathered}[/tex]

After a dilation, the angles remain unchanged, so the measure of angle A will still be 37 degrees.
