If I get your meaning, you want to know how to find the value of sine, cosine, tangent.
SOH CAH TOA
i.e. sine = opposite/hypotenuse, cosine = adjacent/hypotenuse, and tangent = opposite/adjacent
For sine, cosine, tangent, use the mnemonic:

In addition to sohcahtoa, here are two other mnemonics I've heard:
Old Horses Are Horses Over Age:
sin = O/H
cos = A/H
tan = O/A

remember these phrase ...
SOH KAH TOA ...
s=sine
o=opposite
h=hipotenus
K=kosine
A=adjacent
T=tangent ...
SOH = sine = opposite/hipotenus
KAH = cosine = adjacent/hipotenus
TOA = tangent = oppositen/adjacent ...
