Question

In this diagram below, DE is parallel to XY. What is the value of y?

Answer 1

A, or 122. When you know those two lines are parallel with that one line intersecting them both, their larger angles will be equal and their smaller angles will also be equal to each other. 

Answer 2

Answer: The value of y is 122°

Explanation:

Since we have given that

DE is parallel to XY

So, Corresponding angles will be equal and vertically opposite angles are equal too.

So, x=122° (∴ Vertically opposite angles are equal )

and x=y=122° (∵ Corresponding angles are equal )

Hence, The value of y is 122°
