Expert Answer:

 
Let ABCD be a parallelogram where angle A = 70º
In parallelogram opposite angles are congruent. Hence, angle A = angle C = 70º
Also in parallelogram adjacent angles are supplementary.
angle A + angle B = 180º
70º + angle B = 180º
angle B = 180º - 70º = 110º 
angle B = angle D = 110º     opposite angles are congruent.
