Cosine is
(adjacent)/(hypotenuse) which applies to a right triangle. I hope that helps you.

Cosine is one of the three part for trigonometry.

You have sin, cos, and tan.

You can easily do this by understanding SOH CAH TOA.

Sin = OPPO. over HYPOTENUSE
Cos = ADJACENT over HYPOTENUSE
Tan = OPPO. over ADJACENT

I hope this helps!
