Given:
∆ ABC;
angle A = 60.25 °;
angle B = 72.87 °;
angle C =?
Decision.
The sum of all angles in a triangle is 180 °. Then:
angle A + angle B + angle C = 180 °;
angle C = 180 ° – (angle A + angle B);
angle С = 180 ° – (60.25 ° + 72.87 °);
angle C = 180 ° – 133.12 °;
angle C = 46.88 °.
Answer: 46.88 °
