Question

estimate the measure of this angle within 10°.

Explanation:

Step1: Recall angle types

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

Step2: Estimate within \(10^{\circ}\)

By visual comparison (e.g., thinking of common angles like \(90^{\circ}\), \(120^{\circ}\), \(150^{\circ}\)), this angle looks close to \(110^{\circ}\).

Answer:

\(110\)
