estimate the measure of this angle within 15°.

estimate the measure of this angle within 15°.
Answer
Explanation:
Step1: Recall angle - size references
A right - angle is 90°. This angle is less than a right - angle.
Step2: Make an estimate
Based on common angle - size knowledge, this angle looks to be around 45° (since it is approximately half of a right - angle). And 45° is within the 15° tolerance range for a reasonable estimate of this acute angle.
Answer:
45
