In the diagram below ab is parallel to cd what is the value of y?

Answer-

The value of y is 45°

Solution-

When two lines are crossed by another line (i.e the transversal), a pair of angles

are called Alternate Exterior Angles.

When the two lines are parallel Alternate Exterior Angles are equal.

So, in this case the two highlighted angles are Alternate Exterior Angles and as given that AB || CD, so y=45°

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.
