Question

estimate the measure of this angle within 10°. submit

Explanation:

Step1: Recall angle types

A right angle is \(90^\circ\), straight is \(180^\circ\). The angle here is obtuse (greater than \(90^\circ\), less than \(180^\circ\)).

Step2: Estimate the angle

Compare to right angle (\(90^\circ\)) and straight (\(180^\circ\)). This angle looks like \(100^\circ\) (within \(10^\circ\) of actual, likely around \(100^\circ\) as it's a bit more than right angle, but common estimate for such angle is \(100^\circ\) or \(110^\circ\), but \(100^\circ\) is reasonable within \(10^\circ\) error).

Answer:

\(100^\circ\) (or \(110^\circ\), but \(100^\circ\) is a common estimate for this angle within \(10^\circ\) of actual measure)
