Question

find m∠krl. m∠krl = □°

Explanation:

Step1: Identify right - angle

$\angle HRP = 90^{\circ}$

Step2: Use angle relationship

Since $\angle QRL$ and the $50^{\circ}$ angle are vertical angles, $\angle QRL=50^{\circ}$. And $\angle KRL+\angle QRL = 90^{\circ}$. So $m\angle KRL=90 - 50=40^{\circ}$

Answer:

$40$
