In triangle ABC, angle A is 50 degrees and angle B is 12 times less than angle C. What is the degree measure of angle C.

If you add up all the angles in any triangle, you always get 180 °. This is one of the properties of a triangle. Let’s solve the problem using the equation, where:

x ° – angle С;

12x ° – angle B (since it is 12 times larger than angle C);

Let’s compose and solve the equation:

∠ A + ∠ B + ∠ C = 180 °;

50 + 12x + x = 180;

50 + 13x = 180;

13x = 180 – 50;

13x = 130;

x = 130/13;

x = 10 ° – angle C.

Answer: 10 °
