Question

estimate the measure of this angle within 10°. image of a straight angle and a box for input with degree symbol submit

Explanation:

Step1: Identify the angle type

The angle is formed by a straight line, so it's a straight angle. A straight angle measures \(180^\circ\).

Step2: Check the estimation range

The problem asks to estimate within \(10^\circ\), and \(180^\circ\) is within \(10^\circ\) of itself (since \(180 - 10 \leq 180 \leq 180 + 10\) is true as \(170 \leq 180 \leq 190\) and \(180\) is in this range).

Answer:

\(180^\circ\)
