Question

two parallel lines are crossed by a transversal. what is the value of y? o y = 30 o y = 50 o y = 110 o y = 130

Explanation:

Step1: Identify angle - relationship

When two parallel lines are crossed by a transversal, corresponding angles are equal.

Step2: Match angles

The angle of 50° and the angle with measure y° are corresponding angles. So y = 50.

Answer:

y = 50
