Question

in the figure,find the value of x and y

Answer 1

AB||CD and AC is the transversal so,
X=40°(alt.int.angles)
y=30°(alt.int.angles)

Answer 2

In this figure it is given that AB parallel to DC and AD parallel to BC.

Therefore,
AC is the transversal.

Therefore,
By Alternate interior angle test,
x=40*
And
y=30*
