Question

what is the measurement of this angle?

Explanation:

Step1: Read the protractor scale

The protractor has two sets of scales. Since one side of the angle is aligned with \(0^{\circ}\) on the outer - scale, we read the outer - scale where the other side of the angle points.

Step2: Determine the angle measure

The other side of the angle points to \(55^{\circ}\) on the outer - scale.

Answer:

\(55\)
