1. ## 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,

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