Question

△mnp≅△qst. what is m∠s? enter your answer in the box.

Explanation:

Step1: Recall property of congruent triangles

Corresponding angles of congruent triangles are equal. So $\angle S$ corresponds to $\angle N$ in $\triangle MNP\cong\triangle QST$.

Step2: Identify angle - measure

Given $m\angle N = 78^{\circ}$, then $m\angle S=m\angle N$.

Answer:

$78$
