Question

question 3 of 25 which of the following is the measure of an acute angle? a. 126° b. 90° c. 86°

Explanation:

An acute angle is defined as an angle whose measure is greater than \(0^{\circ}\) and less than \(90^{\circ}\).

• Option A: \(126^{\circ}\gt90^{\circ}\), so it is an obtuse angle.
• Option B: \(90^{\circ}\) is a right - angle.
• Option C: \(0^{\circ}\lt86^{\circ}\lt90^{\circ}\), so it is an acute angle.

Answer:

C. \(86^{\circ}\)
