In triangle ABC, angle A = 60.25 °, angle B = 72.87 °, find the value of angle C.

Find the value of the angle of the triangle;

Consider this task and analyze it;

By condition, we are given two angles of a triangle, which means that using the rule of angles of any triangle, we can find the third angle;

Let’s remember the rule of angles of any triangle;

In any triangle, the sum of all angles is always the same and equal to 180 °.

Knowing that the sum of all angles is 180 °, we write the following equation;

A + B + C = 180 °.

Where A, B and C are the angles of the triangle;

From this formula, we express the angle C;

C = 180 ° – A – B;

Substitute the values;

C = 180 ° – 60.25 ° – 72.87;

C = 46.88 °.
