Cosine

For this equation, you need to find the **Cosine(cos)** button on your
calculator. This will help you find the adjacent side of your
triangle. For this image,lets say you need
to find side A and you know angle b. You should set up your
equation as **cos(b)=A/H**. Then you put
**cos(b)**over 1. Next, cross multiply
**cos(b)** by the length of the **Hyp, or H**
. This should bring you to the equation **A=cos(b)xH** and
that is how you find the Adjacent.To see how to solve for Hypotenuse
