Here is the answer:-

given: ABCD is a trapezium and angle B is120*

since, AB||DC and BC is transversal.

then, B+C=180*(co interior angles)

120*+C=180*

C=180*-120*

=60*.

C=60

A= 90( sum of all interior angle is 360)

B=120

C= 60

D=90 (It is a right angle)

90 +90+ 120+60=360

B=120

C= 60

D=90 (It is a right angle)

90 +90+ 120+60=360
