Which trig ratio is adjacent over hypotenuse?

Explanation:
Cosine is the ratio of the length of the side that touches the given angle (the adjacent side) to the hypotenuse. In a right triangle, for a chosen non-right angle, the three basic ratios are defined as: sine = opposite over hypotenuse, cosine = adjacent over hypotenuse, tangent = opposite over adjacent. So the ratio of adjacent over hypotenuse is cosine. For example, in a 3-4-5 triangle, if the adjacent side to the angle is 4 and the hypotenuse is 5, cosine = 4/5. (Sine would be 3/5, tangent would be 3/4, and cotangent would be 4/3.)
