Question

parallel lines r and s are cut by two transversals, parallel lines t and u. how many angles are alternate exterior angles with angle 5?

Explanation:

Step1: Recall alternate - exterior angles definition

Alternate - exterior angles are outside the two parallel lines and on opposite sides of the transversal.

Step2: Identify angles relative to angle 5

For parallel lines \(r\) and \(s\) cut by transversals \(t\) and \(u\), the angles alternate - exterior to angle 5 are angle 15 and angle 11.
