Question

1. choose the best answer. use your protractor on the monitor to find the measure of the angle. 90 degrees 130 degrees 40 degrees 85 degrees

Explanation:

Step1: Recall Protractor Usage

To measure the angle, align the protractor's center with the vertex of the angle, and one side with the protractor's baseline. Then read the measure of the angle from the protractor scale. The angle shown is an obtuse angle (greater than 90° but less than 180°).

Step2: Evaluate Options

• 90° is a right angle, not obtuse.
• 130° is obtuse (between 90° and 180°).
• 40° and 85° are acute (less than 90°). So the most probable measure is 130 degrees.

Answer:

130 degrees (corresponding to the option: 130 degrees)
