Question

a figure containing ∠cde is dilated by a scale factor of 5 to form a new figure which contains ∠cde. ∠cde measures 119°. what is the measure of ∠cde? answer attempt 1 out of 10 m∠cde =

Explanation:

Step1: Recall dilation property

Dilation preserves angle - measure.

Step2: Determine angle measure

Since $\angle CDE$ is dilated to $\angle C'D'E'$ and dilation preserves angle - measure, $m\angle CDE=m\angle C'D'E' = 119^{\circ}$.

Answer:

$119$
