Question

estimate the measure of this angle within 10°. angle image

Explanation:

Step1: Identify the angle type

The angle is formed by two perpendicular lines (one horizontal, one vertical), which is a right angle.

Step2: Recall right angle measure

A right angle measures \(90^\circ\). Since we need to estimate within \(10^\circ\), \(90^\circ\) is within that tolerance.

Answer:

\(90^\circ\)
