Find the angles of triangle ABC if angle A = 65, Angle B = 57.

Given:
ABS triangle,
angle A = 65 degrees,
angle B = 57 degrees.
Find the degree measure of the angle C -?
Solution:
Consider an ABS triangle. We know that the sum of the degree measures of any triangle is 180 degrees. Consequently:
angle A + angle B + angle C = 180;
angle C = 180 – (angle A + angle B);
angle C = 180 – (65 + 57);
angle C = 180 – 122;
angle C = 58 degrees.
Answer: the degree measure of the angle C = 58 degrees.
