Question

In the diagram below, AB is parallel to CD. What is the value of y?

Answer 1

y= 45 because the angle by d is the same exact angle hope this helps

Answer 2

Option B is correct.

y=45

Explanation:

We have been given two parallel lines: AB || CD

And a line that cuts two parallel lines is a transversal line.

And Angles on the transversal are alternate interior angles which are equal.

Please look at the attachment to get the label of angles.

∠1=∠2

y=45

Therefore, Option B is correct.
