Cosine is [latex] \frac{adjacent}{hypotenuse} [/latex] 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!
