The Law of Sines

Sin A/a = Sin B/b = Sin C/c

-the only way to use this formula, is unless you have a pair (meaning an angle and its corresponding side)
-you plug in the factors that can be accounted for
-you use cross-multiplication to get the formula in a horizontal equation
-you use algebra to finish the equation

The Law of Cosines

opposite leg^2 = adjacent leg^2 + other leg^2 -2(adjacent leg)(other leg)cos*

-this equation is a guide to help solving this certain types of triangles
-plug in the factors that you know of into the equation
-if you have to, you are allowed to renovate the equation to be accessible to various occasions
-you use algebra to finish the equation

Area of a triangles that are not Right angles

1/2(leg)(leg)sin*

Sin = Opposite/Hypotenuse
Cos = Adjacent/Hypotenuse
Tan = Opposite/Adjacent
Csc = Hypotenuse/Opposite
Sec = Hypotenuse/Adjacent
Cot = Adjacent/Opposite
