Answer 1

An angle of a quadrilateral measures five-third of a right angle and other three angles are equal.Find the measure of each of the equal angles.​

 

Expert Answer:

Let x be one the three equal angles.

Sum of all the angles of a quadrilateral = 360o

⇒ x + x + x + 120o = 360o

⇒ 3x = 360o -120o

⇒ 3x = 240o

⇒ x = 80o

Thus, the measure of each of the equal angle is 80o
