    would it be 15 x sin 48.5?

    No, think this way, it is going to be longer than 15.0 meters. Multiplying by the sin 48.5 degrees would result in something less than 15. But you are using the correct function just using it the wrong way.

    i don't know then.... because you are suppose to use the opposite of the degree and hypotenuse........ so you would use Soh Cah Toa..... so i use sin = opposite/hypotenuse?

    Yes but it is SOH which means Opposite/over the Hypotenuse Sin 48.5 = O/H Sin 48.5 = 15/H Solve for H
