Question

In a trapezium ABCD,AB is parallel toCD. If angleD=50°,then angleA=

Answer 1

Given: trap ABCD, AB || CD, angle D = 50°

To find : angle A

solution : angle A + angle D = 180°

{sum of co-interior angles is 180°}

angle A + 50 = 180

angle A = 180 - 50

angle A = 130°

hope it helps!☺

Answer 2

Answer:

A=130

Step-by-step explanation:

ab parallel to cd

ad is a transversal

so,

d+a=180°

50°+a=180°

a=130°
