Question

one angle of a quadrilateral is 120 degree and the other three angles are equal.Find the other three angles.

Answer 1

let the other angles be X.

3x + 120 = 360.

= 3x = 240

x = 80 degree ans.

Answer 2

Hii...

The sum of measure of all angles of quadrilateral is 360°

according to condition...

x+x+x+120°=360°

3x+120°=360°

3x=240

x=80°


Angles of quadrilateral are 80°,80°,80°
