Question

question 9 of 15
classify the angle according to its measure.
a. straight
b. acute
c. right
d. obtuse

Explanation:

Step1: Recall angle definitions

• A straight angle is \(180^{\circ}\).
• An acute angle is \(0^{\circ}<\theta < 90^{\circ}\).
• A right angle is \(\theta = 90^{\circ}\).
• An obtuse angle is \(90^{\circ}<\theta < 180^{\circ}\).

Step2: Estimate the angle measure

From the protractor, the angle is less than \(90^{\circ}\).

Answer:

B. Acute
