Question

three angles of a quadrilateral are equal the fourth angle measure 120 degree find the measure of of the equal angles​

Answer 1

Given That = Three angles of a quadrilateral are equal and the fourth angle is of 120 degree

To Find = The measure of the three equal angles

Solve:- Let the angle be (x)

x+x+x+120 = 360

3x+120 = 360

3x = 360 - 120

3x = 240

x = 240/3

x = 80

The measure of other three angle is of 80 degree
