Question

two angles of a quadrilateral are of massive 80 degree angle 110 degree and other two angles are equal what is measure of each equal angle​

Answer 1

Answer: 85 degree each

Explanation:

By Angle sum property of a quadrilateral

Sum of angles = 360degree

Given,  angle 1 = 80 degree

           angle 2 = 110 degree

            other two angles are equal

let Angle 3 = angle 4 = x

angle 1 + angle + 2  angle 3 + angle 4 = 360 degree

80 + 110 + x + x = 360 degree

190 + 2x = 360

2x = 360-190

x = 170/2

x = 85

Angle 3 = angle 4 = 85 degree
