Trigonometry: Co-terminal Angles | Unusual/Negative Angles

Coterminal angles are those angles that share the terminal side of an angle occupying the standard position. The standard position means that one side of the angle is fixed along the positive x-axis, and the vertex is located at the origin.
Trigonometry, is a branch of mathematics,
concerned with specific functions of angles and their application to calculations. There are six functions of an angle commonly used in trigonometry. Their names are sine, cosine, tangent, cotangent, secant, and cosecant.
Trigonometric Functions of Angles Greater than 360 Degrees Or Negative Angles.
These six trigonometric functions in relation to a right triangle are displayed in the Video.
Trigonometric functions are used in obtaining unknown angles and distances from known or measured angles in geometric figures.
In this video, we are to discuss the trigonometric ratios.
Trigonometric Ratios are applicable only for a right-angle triangle. A right-angle triangle is a special triangle in which one angle is 90° and the other two are less than 90°. Furthermore, each side of the right angle triangle has a name.which are the hypotenuse,the adjacent and the opposite sides.

How did you get the final answer without using calculator?

[@AVITECHNOLOGIES]

I have earlier treated special angles. The angles in the question have their special values, hence I don't need a calculator.

[@FavourAmodu-cg6tw]

Ok
