Question

enter the correct answer.
find the measure of the exterior angle, x.
$x = ?^\circ$
the triangle has interior angles $72^\circ$ and $36^\circ$, and $x$ is the exterior angle corresponding to the third interior angle.

Explanation:

Step1: Recall exterior angle theorem

The exterior angle of a triangle equals the sum of the two non-adjacent interior angles.

Step2: Calculate the exterior angle

$x = 72^\circ + 36^\circ$
$x = 108^\circ$

Answer:

$108$
