Question

Two angles of a quadrilateral measure 85º and 75° respectively. The
other two angles are equal. Find the measure of each of these equal
angles.​

Answer 1

Answer:

Sum of all the angles in a quad. is 360°

As both the unknown angles r equal length both of them be x

So here's ur equation

75°+ 85°+2x=360°

2x=360-160

= 200°

x=100°
