    finding tan theta

    The point (12,-16) is on the terminal side of the angle theta, find tan theta.

    Ok so I know you use Pythagoran thereom to find h(hypothe...) so I did this and I came up with -4/3. But this is not an answer choice. Can anyone help?

    Dear tigergirl,

    The hypotenuse is not needed to calculate \tan{\theta}. But your answer is correct,

    \tan{\theta}=\frac{-16}{12}=-\frac{4}{3}

    Hope this will help you.
