    [tex]sin\theta = \frac{opposite}{adjacent}[/tex]
    [tex]cos\theta = \frac{adjacent}{hypotenuse}[/tex]
    [tex]tan\theta = \frac{opposite}{adjacent}[/tex]

    Use the one which contains the unknown variable and the variable you are given.

    Actually, it's:

    [tex]sin\theta = \frac{opposite}{hypotenuse}[/tex] :wink:

    OP, do you know the sine and cosine rules?
