Question

these figures are congruent. what is m∠y?

Explanation:

Step1: Recall congruent - figure property

Corresponding angles of congruent figures are equal.

Step2: Identify corresponding angles

In congruent triangles $\triangle RST$ and $\triangle WXY$, $\angle Y$ corresponds to $\angle T$.

Step3: Determine angle - measure

Since $m\angle T = 53^{\circ}$, then $m\angle Y=53^{\circ}$ because of the congruence property.

Answer:

$53$
