Question

what is the measure of this angle? m∠abc = ?°

Explanation:

Step1: Identify starting and ending points

The ray BC points to 0 degrees and ray BA points to 160 degrees.

Step2: Calculate the angle measure

The measure of angle ABC is the difference between the two - readings. Since we start from 0 degrees (ray BC) and go to 160 degrees (ray BA), the measure of ∠ABC is 160 degrees.

Answer:

160
