Question

find the measure of each angle indicated.
13)
a) 61° b) 140°
c) 91° d) 55°

Explanation:

Step1: Identify the relationship between angles

The given angles are alternate exterior angles. When two parallel lines are cut by a transversal, alternate exterior angles are equal.

Step2: Determine the measure of the unknown angle

Since the alternate exterior angle to the unknown angle is \(61^{\circ}\), the unknown angle is also \(61^{\circ}\).

Answer:

A. \(61^{\circ}\)
