Question Analysis

This question is about measuring an angle with a protractor.

 

Key Concept Explanation

A protractor has two scales. When the angle's initial side aligns with the left - hand 0 - degree mark, we use the outer scale. The angle's measure is where the terminal side crosses the appropriate scale.

 

Step - by - Step Solution

1. First, identify the correct scale:

The initial side of the angle is aligned with the  mark on the left - hand side of the protractor, so we should use the outer - ring scale for measurement.

 

2. Then, read the measurement:

Looking at where the terminal side of the angle crosses the outer - ring scale of the protractor, it intersects at
