Answer 1

Here.
MNOP is a Quadrilateral.
and

angleO=57°
angleN=angleM=90°


By angle sum prpty of Quadrilateral...

360°=Angle(O+N+M+P)
→360°=57°+90°+90°+angleP
→AngleP=360°-237°
→AngleP=123°

Hope it helps....

Answer 2

Hey dear.....

In this figure MPNO is a quardrilateral.
Given angle MON =57 degrees.
angle ONP=90 degrees.
angle PMO=90 degrees.

Let angle MNP be x

According to question....

=>57 +90+90+x=360{Sum of all angles in a quardrilateral is 360 degrees.}
=>237+x=360
=>x=360-237
=>x=123 degrees.

Hope it helps....
