Question

find the measure of angles a, b, c, and d. progress: 0/4 part 1 of 4 m∠a=□°

Explanation:

Step1: Analyze the given angles

We are given two angles \(15^{\circ}\) and \(17^{\circ}\). Angle \(a\) is composed of these two angles.

Step2: Calculate the measure of angle \(a\)

By the angle - addition postulate, \(m\angle a=15^{\circ}+17^{\circ}\)

Answer:

\(32\)
