| 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 °.
