Question

1. find the measure of the mixing angle.

$x^{circ} = \underline{\quad\quad}$

Explanation:

Step1: Recall triangle angle sum rule

The sum of angles in a triangle is $180^\circ$.

Step2: Calculate the unknown angle

Subtract known angles from $180^\circ$.
$z = 180 - 116 - 32$

Answer:

$48^\circ$
