I can't find any of these angles that are equivalent to the basic angles. Thanks

A trigonometric equation is an equation that involves trigonometric functions, such as sine, cosine, and tangent. These equations are typically used to solve for unknown angles or values in a right triangle.
The process for solving a trigonometric equation involves using trigonometric identities, such as the Pythagorean identity and the double angle identity, to simplify the equation and then using inverse trigonometric functions to find the solutions.
The main difference between solving a trigonometric equation and solving a regular algebraic equation is that trigonometric equations involve trigonometric functions, which have specific properties and identities that must be used in the solving process. Algebraic equations, on the other hand, only involve basic arithmetic operations.
The purpose of solving a trigonometric equation is to find the values of unknown angles or sides in a right triangle, or to find solutions for real-life problems that involve trigonometry, such as determining the height of a building or the distance between two points.
You can check the validity of your solution by plugging it back into the original equation and seeing if it satisfies the equation. Additionally, you can use a calculator to graph the equation and visually confirm that your solution is correct.
