Use the Triangle Angle-Sum Theorem.

$83.1$

Practice makes perfect

We have been given the measures of the two angles of a triangle,

44.7

and

52.2 .

We will find the measure of the third angle using the Triangle Angle-Sum Theorem. This theorem tells us that the measures of the interior angles of a triangle must add to

18 0^{\circ} .
