Finally, if you know the opposite and adjacent sides, the tangent function is the correct choice for your calculations. By selecting the correct trigonometric function—sine, cosine, or tangent—you can establish an equation that relates these sides to the target angle.

Furthermore, be aware that trigonometric functions are periodic, meaning multiple angles can have the same ratio, though the context of the problem usually indicates the specific angle you are seeking. Identifying the Correct Function To use trig to find angles, you must first identify which two sides you know.
Sine is the ratio of the opposite side to the hypotenuse, cosine is the ratio of the adjacent side to the hypotenuse, and tangent is the ratio of the opposite side to the adjacent side. Understanding the Core Trigonometric Ratios The foundation for finding angles lies in mastering the three primary ratios defined for a right triangle.

If you know the lengths of the side opposite the angle and the hypotenuse, you use the sine function. Trigonometry provides a direct method to find unknown angles within right-angled triangles using the ratios of the sides.
