Question

Two angles of a quadrilateral are 89° and 113°. If the other two angles are equal, find the equal angles.​

Answer 1

Step-by-step explanation:

[ 360° - (89°+113°) ] / 2 = 158°/2 = 79°

Steps:

Let the equal angles are x

So we know sum of all angles of quad. is 360°

x + x + 89° + 113° = 360°

2x = 158°

x = 79°

ANS.

Hope you get it. Best of Luck
