Transcript text: Find $m \angle A B C$. Then classify the angle.

Solution

Solution Steps

Step 1: Identify the Angle

To find the measure of angle $ \angle ABC $, we need to look at the protractor and identify the points A, B, and C. Point B is the vertex of the angle, and points A and C are on the arms of the angle.

Step 2: Measure the Angle

Using the protractor, align the baseline with line BC and ensure that point B is at the center of the protractor. Read the measurement where line BA intersects the protractor scale.

Step 3: Determine the Angle Measurement

From the protractor, line BA intersects at 40 degrees. Therefore, the measure of $ \angle ABC $ is 40 degrees.

Step 4: Classify the Angle

An angle that measures less than 90 degrees is classified as an acute angle. Since $ \angle ABC $ measures 40 degrees, it is an acute angle.
