Question

35. In parallelogram ABCD, find angleB. angle Cand angle D
a =80degree​

Answer 1

Answer:

Step-by-step explanation:

Angle B = Angle D (Opp angles of a //gm are equal) - 1

Thus, Angle D = 80°

Let angles A and C be X (From 1)

80 + 80 + X + X = 180

160 + 2X = 180

2X = 180 - 160

2X = 30

X = 30

X = 30 ÷ 2

X = 15
