Answer 1

Answer:

Sorry for the writing but hope it's helpful

Answer 2

Answer:

80 degree

Step-by-step explanation:

sum of all the angles of a quadrilateral are 360°

and 4th angle is 120°

therefore the sum of other three angles

360-120= 240°

since the three angles are equal.... considering the angle as X

3x= 240

therefore X= 80° ✓
