In a cyclic quadrilateral \( A B C D \), it is being given that \( \angle A=(x+y+10)^{\circ} \),
(W) \( \angle B=(y+20)^{\circ}, \angle C=(x+y-30)^{\circ} \) and \( \angle D=(x+y)^{\circ} \). Then, \( \angle B= \) ?
(a) \( 70^{\circ} \)
(b) \( 80^{\circ} \)
(c) \( 100^{\circ} \)
(d) \( 110^{\circ} \)
