Answer:

$m\angle 5=120^(\circ)$

Explanation:

We have been given that line AB is parallel to CD. The measure of angle 1 is 120 degrees. We are asked to find measure of angle 5.

We know that corresponding angles of parallel lines are always equal.

We can see that angle 5 corresponds to angle 1, therefore, measure of angle 1 will be equal to measure of angle of 5.

$m\angle 5=m\angle 1$

$m\angle 5=120^(\circ)$

Therefore, the measure of angle 5 is 120 degrees.
