Question

what is the measurement of this angle?

Explanation:

Step1: Identify zero - degree line

The zero - degree line of the protractor is aligned with one ray of the angle.

Step2: Read the measurement

We read the value where the other ray of the angle intersects the protractor scale. The angle is measured counter - clockwise from the zero - degree line. The value is $150^{\circ}$.

Answer:

$150^{\circ}$
