Answer 1

Answer:

let the 3 equal angles be 3x

3x + 120 = 360 ( by angle sum property of

Quadrilarerals)

3x = 360 - 120

3x = 240

x = 240/3 = 80

Answer 2

Answer:

let the three equal number be x,x,x

according to the question,

x+x+x+120°=360° (the sum of all angles of quadrilateral is 360°)

3x=360-120

3x=240

x=240/3

x=80°

all three angles are equal so,they are of 80°
