​

Answer 1

Answer:

Angle B = 130 degree

Angle C = 50 degree

Angle D = 130 degree

Step-by-step explanation:

Angle A = 50 degree

Angle C = Angle D ( because opposite angles are equal)

So angle C = 50 degree

Angle B = 180 degree - 50 degree ( by linear pair)

So angle B = 130 degree

Angle B = Angle D( because opposite angles are equal)

So angle D = 130 degree
