Question

Two angles of a quadrilateral are in 70 degree and 120 degree .the two angles are equal.find the measure of equal angle

Answer 1

let the angle which are equall =x
then
70+120+x+x=360
190+2x=360
2x=360-190
2x=170
x=170/2
x=85
hence equall angles are 85

Answer 2

both the two angles would be 85 degree
