Question

1. choose the best answer. use your protractor on the monitor to measure the angle. answer may vary. get as close to the answer as possible. 120° 90° 60° 30°

Explanation:

Step1: Recall Protractor Use

To measure an angle with a protractor, align the center of the protractor with the vertex of the angle, and one side with the 0° mark. Then read the measure of the other side.

Step2: Analyze the Angle (Visual Estimate)

The angle appears obtuse (greater than 90° but less than 180°). Among the options, 120° is obtuse, 90° is right, 60° and 30° are acute. So 120° is the most likely.

Answer:

120° (Note: Since it's a measurement, the actual value may vary slightly, but 120° is the best option here.)
