What are sine, cosine, and tangent, and how are they used to find the lengths of sides in a right triangle?

Sine, cosine, and tangent are trigonometric functions that relate the angles of a right triangle to the lengths of its sides. Sine (sin) is the ratio of the length of the opposite side to the hypotenuse. Cosine (cos) is the ratio of the length of the adjacent side to the hypotenuse. Tangent (tan) is the ratio of the length of the opposite side to the adjacent side. These functions are used to find unknown side lengths when one side length and one angle are known.
