Question

Three angles of a quadrilateral are equal and measure of the fourth angle is 60degree . Find the measure or each equal angles

Answer 1

Step-by-step explanation:

Let the other equal angles be x

By the angle sum property of a quadrilateral,

x+x+x+60 = 180

3x + 60 = 180

3x= 120

x= 120/3

x= 40

Answer 2

Step-by-step explanation:

Let x be the 3 equal angles. We know, Sum of all the quadrilateral is 360 degree. thus, the measure of each of the equal angles is 100 degree .
