The angles of a triangle always sum to 180 degrees. We can use this fact to solve for the missing angle of a triangle.

Q1. In triangle ABC below, angle A = 30 degrees and angle B = 70 degrees. What is the measure of angle C?
Q2. If a triangle is equiangular, what is the degree measure of each of its angles?
Q3. The degree measures of the angles of a triangle are in the ratio 2 : 3 : 9 What is the degree measure of the SMALLEST angle of the triangle?
