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 \(90^{\circ}\), an obtuse angle is between \(90^{\circ}\) and \(180^{\circ}\). This angle is obtuse.

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

Common angle benchmarks: \(90^{\circ}\), \(120^{\circ}\), \(135^{\circ}\), \(150^{\circ}\), \(180^{\circ}\). This angle looks close to \(135^{\circ}\).

Answer:

\(135^{\circ}\)
