If we want know CosT= ____

First, we have to know what is Cos? Cos is Cosine and Cosine=Adjacent/hypotenuse.

Then, Now we know this ratio, so we can find it . But before we find it, we must write adjacent, opposite and hypotenuse on the triangle. I know hypotenuse is a longest side, opposite is the line cross from the angleT, and adjacent is next to the angleT.

**Last, Now we put the number instead the letter.**

Cos=adjacent/hypotenuse

Cos=20/52

cos=0.38

So CosT=0.38
