Question

these figures are congruent. what is m∠y?

Explanation:

Step1: Recall congruent - triangle property

Corresponding angles of congruent triangles are equal.

Step2: Identify corresponding angles

In congruent triangles $\triangle EFG$ and $\triangle WXY$, $\angle Y$ corresponds to $\angle G$.

Step3: Find the measure of $\angle Y$

Since $m\angle G = 43^{\circ}$, then $m\angle Y=43^{\circ}$.

Answer:

$43$
