Question

ABCD is a trapezium in which AB II DC . If < A = < B = 40 , what are the measures of other two angles

Answer 1

is any length given between the parallel lines or is the length of the line given bcoz its impossible to find this only one the fact that angle A and B =40 degree.there must be some more information.

Answer 2

<A=<B=40then sum of trapezium =180
let all angle to be x then
x+x+x+x=180
<A+<B+2x=180

40+2x =180 then
2x=180-40
2x=140
x= 140/2
x=70
