Question

1. the exterior angles of this triangle are all equal. what is the measure of angle x°?

options: 90°, we need more information to solve this problem, 360°, 120°

Explanation:

Step1: Recall exterior angle sum rule

The sum of all exterior angles of any polygon is $360^\circ$.

Step2: Set up equation for triangle

A triangle has 3 equal exterior angles, so $3x = 360$.

Step3: Solve for $x$

$x = \frac{360}{3}$

Answer:

120°
