As per the triangle sum theorem, the sum of all the angles (interior) of a triangle is 180 degrees, and the measure of the exterior angle of a triangle equals the sum of its two opposite interior angles. This theorem is fundamental in geometry and can be used to solve for unknown angles in triangles. In a triangle, if the second angle is 5° greater than the first angle and the third angle is 5° greater than second angle, find the three angles of the triangle. This gives us a total of three angles in the triangle.
