In the adjoining figure , ABCD is a $\parallel$ gm in which $\angle A =75^{\circ}$ Find the measure of each of the angles $\angle B , \angle C$ and $\angle D$

Question

$\begin{array}{1 1} \angle C =75^{\circ}, \angle B= 105^{\circ}, \angle D= 105^{\circ} \\ \angle C =65^{\circ}, \angle B= 75^{\circ}, \angle D= 115^{\circ} \\ \angle C =85^{\circ}, \angle B= 105^{\circ}, \angle D= 45^{\circ} \\ \angle C =95^{\circ}, \angle B= 100^{\circ}, \angle D= 75^{\circ}\end{array}$
