Question

question a figure containing ∠rst is dilated by a scale factor of 1/4 to form a new figure which contains ∠rst. ∠rst measures 116°. what is the measure of ∠rst? answer attempt 1 out of 2 m∠rst = ° submit answer watch video show examples

Explanation:

Step1: Recall dilation property

Dilation preserves angle - measures.

Step2: Determine the measure of the dilated angle

Since the measure of ∠RST is 116° and dilation preserves angle - measures, the measure of ∠R'S'T' is also 116°.

Answer:

116
