Question

estimate the measure of this angle within 15°.

Explanation:

Step1: Recall angle - type benchmarks

A right - angle is 90°. This angle appears to be larger than a 45° angle (half of a right - angle) and smaller than a 90° angle.

Step2: Make an estimate

Based on visual inspection and knowledge of angle benchmarks, we can estimate the angle to be around 75°.

Answer:

75
