Question

ABCD is a trapezium in which AB ‖ CD. If angle A = 60° and angle B = 100°. Find the measure of C and D.​

Answer 1

Step-by-step explanation:

AB I I CD, we have

∠A+∠D=180 (∵ angles at the same side of transversal)

⇒∠D=180 ∘

−60 ∘

=120 ∘

Answer 2

Answer:

Step-by-step explanation:

A triangle has 180°

Angle A = 60°

Angle B =100°

Angle C = 100 + 60° = 160°

= 180° - 160° = 20°
