Use the image to answer the question.
An illustration shows a triangle with vertices as A B C. Angle A on top is 103 degrees and angle B on the left is 22 degrees. Vertex C is on the right.
Use the Triangle Angle Sum Theorem to find the measure of the third angle of the triangle shown.
First, let's find the measure of angle C using the Triangle Angle Sum Theorem:
The Triangle Angle Sum Theorem states that the sum of the interior angles of a triangle is always 180 degrees.
So, we can find the measure of angle C by subtracting the sum of angles A and B from 180 degrees:
180 - 103 - 22 = 55
Therefore, the measure of angle C is 55 degrees.
