Question

what is the measurement of the angle shown below? 30° 60° 180° 150°

Explanation:

Step1: Read the protractor

When using a protractor, we check where the terminal side of the angle aligns with the scale. The angle is measured from the initial side (the straight - line side of the angle).

Step2: Determine the angle measure

The initial side is aligned with the \(0^{\circ}\) mark on the outer scale (assuming we follow the correct orientation of the protractor for this angle). The terminal side aligns with the \(150^{\circ}\) mark on the outer scale.

Answer:

\(150^{\circ}\) (the fourth option)
