Triangle ABC is a right triangle. Angle A is a right angle, M∠B = 10× - 8, and M∠C = 4× + 28. What is M∠C?

The correct answer is C. If two angles of one triangle are congruent to two angles of another triangle, then the third pair of angles is also congruent

Explanation:

In mathematics, the third angle theorem state if two angles of one triangle are congruent or equivalent to two angles of another triangle the third angle of both of the triangles would be the same. This can be explained because in a triangle the sum of all the angles is always 180° and therefore if you know two of the angles the third angle can be determined and if in two triangles two angles are the same the third will also be same for both. Therefore, according to the third angle theorem "if two angles of one triangle are congruent to two angles of another triangle, then the third pair of angles is also congruent".
