Question

What is the ratio for Cosine?

Answer 1

In a right triangle, the cosine of an angle is the ratio of the length of the side adjacent to the angle divided by the length of the hypotenuse of the triangle. Figure 20.7 A right triangle with tangent ratio 9/14. sin ∠A = 9√277/277 and cos ∠A = 14√277/277.
