Question

ABCD is a parallelogram in which AB parallel to DC and AB parallel to BC find angle b,c, and d​

Answer 1

50 +130=180

therefore angle b =d=130

and angle c=a=50 degree

Answer 2

Answer:

Firstly i would like to tell you that AB and DC are parallel but AB is not parallel to BC

your answer is

Angle A = 50° as already given

According to, interior angles on the same side of the transversal are supplementry Angle A+Angle B=180°

Therefore Angle B= 180°-50°

Angle B= 130°

And,

According to vertically opposite angle property,

Angle C= 50°

Angle D= 130°

Hope it helps you
