# For Review Exercises 12 to 15 , find the values of x and y . To determine

To find:

The values of x and y.

Explanation

Given:

Line a is parallel to line b.

Figure (1)

Property:

(1) If two parallel lines are cut by a transversal, then a pair of corresponding angles is congruent.

(2) The measure of an exterior angle of a triangle equals the sum of the measures of the two nonadjacent interior angles.

Approach:

Line a is parallel to line b.

120° and x are congruent corresponding angles.

So,

x=120°.

The measure of an exterior angle of a triangle equals the sum of the measures of the two nonadjacent interior angles
