Question

In a trapezium ABCD , with AB||CD. If angle A= 100° then angle D??

Answer 1

Answer:

80

Step-by-step explanation:

In a trapezium ABCD

Given AB//CD

So A and D are the opposite angles i.e A+D= 180

B and C are the opposite angles i.e B+C= 180

A and B are equal angles A = B

C and D are equal angles C = D

Given A = 100 degrees

A+D= 180

100 + D = 180

D = 180 - 100

D = 80
