w.k.t , the sum of angles of a quadrilateral is 360 degrees
if 120° is d greatest angle & the angles are in AP , then the other three angles are
120°- d , 120°- 2d , 120° - 3d
120°+120°-d+120°-2d+120°-3d = 360°
480° - 6d = 360°
6d = 120°
d = 20°
so the other three angles are 100° , 80° , 60°
if 120° is d greatest angle & the angles are in AP , then the other three angles are
120°- d , 120°- 2d , 120° - 3d
120°+120°-d+120°-2d+120°-3d = 360°
480° - 6d = 360°
6d = 120°
d = 20°
so the other three angles are 100° , 80° , 60°
