Trigonometric Ratios

Question

What trigonometric ratio corresponds to the ratio of the side adjacent to the acute angle in a right triangle to the side opposite to it?​ Please explain your answer.

Answer 1

In a right triangle, the hypotenuse is the longest side, an "opposite" side is the one across from a given angle, and an "adjacent" side is next to a given angle. We use special words to describe the sides of right triangles. The hypotenuse of a right triangle is always the side opposite the right angle. It is the longest side in a right triangle.

In a right angled triangle, the cotangent of an angle is: The length of the adjacent side divided by the length of the side opposite the angle.
