Given:

Let the quadrilateral be ABCD

where

∠A=50°

∠B=130°

∠C=∠D = x

To find :

∠C and ∠D

Solution :

Sum of all angles of quadrilateral = 360°

∠A+∠B+∠C+∠D =360°

50°+130°+x+x=360°

180°+2x=360°

2x=180°

x=90°

Hence,he measure of each of these equal angles( other two equal adjacent angles ) is 90°
