Question

In parallelogram abcd, angle a = 40 degree find angle d

Answer 1

Answer:

140 °

Step-by-step explanation:

Let , AB and CD are two parallel lines and AD is the transversal .

We know that , angles in same side of the transversal are supplementry ( sum of two angles is equal to 180° ) .

Hence ,

Angle (A) + Angle (D) = 180°

40° + Angle (D) = 180°

Angle (D) = 180° - 40°

= 140°
