Finally, use your knowledge that the angles of all triangles add up to 180 degrees to find angle c. These angles are most commonly and frequently used in trigonometry. Every single teacher despises when you're trying to describe trigonometric functions.

Trigonometric values for arbitrary special angles.

Angles and the unit circle. If the sum of two angles is one right angle or 90°, then one angle is said to be complementary of the other. The above definition applies to negative angles also. The steps are the same as the 1.
