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°

Answer:
Step-by-step explanation: one angle of the quadrilateral is 120 and the total interior angle of the quadrilateral is 360 so 360-120=240 so other 3 angles are 240÷3=80 so all the three angles are equal
