Question

on your own: exterior angles of a tri
enter your answer in the box.
$x = \square$

Explanation:

Step1: Find adjacent interior angle

The exterior angle and its adjacent interior angle are supplementary, so the interior angle is $180^\circ - 106^\circ = 74^\circ$.

Step2: Calculate $x$ via triangle angle sum

The sum of angles in a triangle is $180^\circ$. So $x = 180^\circ - 73^\circ - 74^\circ$.
<Expression>
$x = 180 - 73 - 74 = 33$
</Expression>

Answer:

$x = 33$
