Question Analysis

This question requires measuring an angle using a protractor.

 

Key Concept Explanation

A protractor has two scales (inner and outer), ranging from 0° to 180°. When measuring, align one side of the angle with the 0° mark and read the value where the other side intersects the appropriate scale.

 

Step - by - Step Solution

1. Determine the scale to use:

Since the initial side of the angle is on the  mark on the left - hand side of the protractor, we use the outer - ring scale.

 

2. Read the measurement:

The terminal side of the angle intersects the outer - ring scale at approximately
