Answer:

[tex]\angle A'B'C' = 40[/tex]

Step-by-step explanation:

Given

[tex]\triangle ABC[/tex] and [tex]\triangle A'B'C'[/tex]

Required

The measure of [tex]\angle A'B'C[/tex] after the dilation

Dilation does not change the measure of angle of a shape.

So, we have:

Before dilation

[tex]\angle ABC = 40[/tex]

This implies that: after dilation

[tex]\angle A'B'C' = 40[/tex]
