    which trig function uses the next.to (adjacent) and hypotenuse

    tangent never looks at the hypotenuse; tan = over/nextto whats you next best one?

    cosine is the winner !! now, cosine = next.to/ hypotenuse

    with what is given that leaves us: cos(24) = 11/x can you solve for x?

    manually?? or can i use a calculator?

    youll need a calculator or table to determine cos(24) but just the setup would be useful. How would we move this equation around to solve for x?

    I have NO CLUE, but the calculator is telling me 12.04

    cos(24) = 11/x x = 11/cos(24) and yes, abt 12.04 is what i get as well http://www.wolframalpha.com/input/?i=11%2Fcos%2824%29

    the idea is to find v in order to find w, right?

    itll be quick enough, go ahead and write out the sin cos tan function for me so we can reference them

    sin = Opposite/Hyp. cos = adjacent/ Hyp. tan= opposite/adjacent

    in my mind, over is the same as opposite :)

    so, would you agree that the sine function works best for us on this one?

    sin(65) = v/15 ; v = 15 sin(65) sin(w) = v/21, replacing the value of v we get sin(w) = 15 sin(65)/21 this make sense so far?

    good :) keep in mind that to find w we need to do an inverse sin operation
