Question

The two adjacent angles of a quadrilateral are 80°and 120° . The other two angles are equal . Find them .​

Answer 1

Given that :-

Two angles of quadrilateral are 80 and 120 degrees.

Also,
The remaining two angles are equal.
So
Let them be x

According to the angle sum property of quadrilateral, we have

$80 + 120 + x + x = 360 \\ \\ 2x + 200 = 360 \\ \\ 2x = 360 - 200 \\ \\ 2x = 160 \\ \\ x = \frac{160}{2} = 80$

Hence,

Other two angles are 80 degrees each!
