Question

in △mno, $overline{om}congoverline{no}$ and m∠n = 17°. find m∠m.

Explanation:

Step1: Identify isosceles - triangle property

Since $\overline{OM}\cong\overline{NO}$, $\triangle MNO$ is isosceles and $\angle M\cong\angle N$.

Step2: Determine angle measure

Given $m\angle N = 17^{\circ}$, then $m\angle M=m\angle N$.

Answer:

$17^{\circ}$
