Question

estimate the measure of this angle within 15°.

Explanation:

Step1: Recall angle types

An acute angle is less than \(90^{\circ}\), a right angle is \(90^{\circ}\), and an obtuse angle is greater than \(90^{\circ}\) but less than \(180^{\circ}\). This angle is acute.

Step2: Estimate within \(15^{\circ}\)

Common reference angles: \(30^{\circ}\), \(45^{\circ}\), \(60^{\circ}\). This angle looks closer to \(60^{\circ}\) than \(30^{\circ}\) or \(45^{\circ}\).

Answer:

\(60\)
