Question

ABCD is a trapezium where AB|| DC find x and y ​

Answer 1

Answer:

y=100 degree and x=80degree

Step-by-step explanation:

y=100degree since BC transversal forms alternate angles.

x=180 -100(opposite sides of parallelogram are supplementary)

x=80degree

Answer 2

Answer:

<A+<D=180°[AB||CD]

<D=180°-<A

<D=180°-120°=60°

hence X=60°

now,

<B=<C{alternate angle(AB||CD)}

y=100°
