Use the Triangle Angle-Sum Theorem.

$22$

Practice makes perfect

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

57

and

101 .

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} .
