Sine and cosine - Wikipedia
Once such a triangle is chosen, the sine of the angle is equal to the length of the opposite side divided by the length of the hypotenuse, and the cosine of the angle is equal to the length of the adjacent side divided by the length of the hypotenuse: [1]
Section 4. 3: Right Triangle Trigonometry | Precalculus
In previous examples, we evaluated the sine and cosine in triangles where we knew all three sides But the real power of right-triangle trigonometry emerges when we look at triangles in which we know an angle but do not know all the sides
