Question

estimate the measure of this angle within 10°. angle image: two perpendicular rays, one vertical up, one horizontal right, from a common vertex input box° submit button

Explanation:

Step1: Identify the angle type

The angle formed by two perpendicular lines (one vertical, one horizontal) is a right angle. A right angle is known to measure \(90^\circ\).

Step2: Check the estimation range

The problem asks to estimate within \(10^\circ\). Since the angle is clearly a right angle (perpendicular lines), its measure is \(90^\circ\), which is within the \(10^\circ\) tolerance (as \(90^\circ\) is exactly the right angle measure, and the tolerance allows for a range around it, but here it's exactly \(90^\circ\)).

Answer:

\(90^\circ\)
