Question

what is the measurement of this angle?

Explanation:

Step1: Determine the scale

The protractor has two sets of scales (inner and outer). The angle is measured from \(90^{\circ}\) to \(100^{\circ}\). Each small - scale division on the protractor represents \(1^{\circ}\).

Step2: Calculate the angle

The starting point is \(90^{\circ}\) and the ending point is \(100^{\circ}\). The measure of the angle is \(100 - 90=10^{\circ}\)

Answer:

\(10\)
