Step-by-step explanation:
Here ABCD is parallelogram,
we know that,
sum opposite sides of parallelogram is 180°
so,
angle A + angle B = 180°
let the angle B be x
According to question
120+x=180
x=180-120
x=60°
Now,
Angle A and C = 120°(opposite angle of parallelogram are equal)
Angle B and D =60°(opposite angle of parallelogram are equal)
