    x is the height the hypotenuse side is 14 and the angle is 33degrees

    Depending on whether the x is adjacent or opposite of the angle, use either sin or cos. You can set it up something like this: \[\sin 33 = \frac{x}{14}\] And solve for x. Make sure that you use sin or cos, whichever one is appropriate, though.

    x is oposite to 33degrees and hypothenuse is 14

    So which is appropriate, sin or cos? Which ratio involves both the opposite and the adjacent?

    Not divided by 14.

    Multiply. But yes, sin then 33 then times 14 would do it, and 14 then times then sin 33 should also work.

    14 * sin(33). It's the only solution to the equation above.

    Simpler calculators may require you to do: 33 <sin button> <x button> 14 <=>

    7.6 was correct. I've been using degrees where things expected radians.
