sin20=o/h , cos20=a/h tan 20=o/a

anonymous · Answer

which sides are you given and apply that trig function

anonymous · Answer

how do you know what o/h  a/h  and o/a mean

anonymous · Answer

SOH CAH TOA is the method that you should memorized.
SOH stands for sin(...)=Opposite/Hypotenuse
CAH stands for cos(...)=Adjacent/Hypotenuse
TOA stands for tan(...)=Opposite/Adjacent

Make sense? If you're ever going to be taking any more math classes in your life you really need to memorize that -- super helpful!

In your specific problem you have x and 12 as your sides and no hypotenuse. So which trig function can you use?
