Question

The three angles of a quadrilateral are equal. if the measure of the fourth angle is 120 degree what is the measure of each of the equal angles?​

Answer 1

Answer:

Answer. Let the equal angles be x. Hence, the other 3 angles are 80° each.

Answer 2

Answer:

Measure of aide of Quadrilateral = 360

Let the 3 angles be = 3x

ATQ,

120 +3x = 360

3x = 360-120

3x = 240

x = 240/3

x = 80

The measure of the 3 equal angles is 80.
