Question

what is the measurement of this angle?

Explanation:

Step1: Determine the scale reading

The angle is measured using a protractor. The inner scale is not relevant here. Looking at the outer scale, one ray is at \(10^{\circ}\) and the other is at \(70^{\circ}\).

Step2: Calculate the angle measure

The measure of the angle is the difference between the two scale readings. So we calculate \(70 - 10\).

Answer:

\(60\)
