Question

In trapezium ABCD with AB parallel to CD if,angle A is 100 then angle D is equal to

Answer 1

80........because AB is parallel to CD

Answer 2

Angle D is equal to 80°.

Given,

ABCD is a trapezium. AB║CD.

∠A = 100°

To Find,

Angle D.

Solution,

For AB║CD with transversal AD.

The Sum of interior angles must be equal to 180°.

⇒ ∠A + ∠D = 180°

⇒ 100° + ∠D = 180°

⇒ ∠D = 180° - 100°

⇒ ∠D = 80°

Hence, angle D is equal to 80°.
