Question

7. Three angles of a quadrilateral are equal and the measure of the fourth angle is 120°. Find
the measure of each of the equal angles.​

Answer 1

Answer:

80 degree

Step-by-step explanation:

Since each angle are equal we can consider them as X so,

3x + 120 = 360

3x = 360-120= 240

3x = 240

x= 240/3

so, x= 80
