The cosine function is the ratio of the side ADJACENT to the hypotenuse.
another way, the cosine equals the adjacent (adj) side divided by the hypotenuse
(hyp). Complete the following formula: cos =
cos = adj
The cosine function is the ratio of the length of the "side adjacent to the length of the
hypotenuse. This relationship remains the same as long as the angle does not change.
Solve for cos in the following triangles:
cos 1 = _______
cos 2 = _______
