Answer 1

Answer:

a = 120° [Interior angles on the same side of transversal]

b = 60° [║lines opposite alternate angles are equal]

c = 60° [Vertically opposite angles (b=c)]

d = 120° [Linear pair]

HOPE THIS HELPS :D

Answer 2

Answer:

here, a + 60 degree = 180 degree (interior angles are supplementary)

         a = 180 - 60 degree

         a = 120 degree

a = d = 120 degree (alternate angles)

d + b = 180 degree (linear pair)

120 degree + b = 180 degree

b = 180 - 120 = degree

b = 60 degree

b = c = 60 degree (vertically opposite angles)

hence, a = 120 degree

            b = 60 degree

            c = 60 degree

            d = 120 degree

Hope it helps...
