Question

what is the measure of this angle? m∠ab

Explanation:

Step1: Determine the scale reading

When measuring an angle with a protractor, we look at the scale. Here, the non - zero arm \(BA\) is pointing to the \(60\) degree mark on the outer scale (assuming the standard protractor usage where one arm is at \(0\) and we measure the angle between the two arms).

Answer:

\(m\angle ABC = 60^{\circ}\)
