    Help with simple tangent problem

    I know I am missing something simple. tan\theta=\frac{-1}{2} Having a hard time figuring out what \theta is.

    Look at a 30-60-90 right triangle. Alternatively use the definition  \tan \theta = \frac{\sin \theta}{\cos \theta} .

    This one doesn't come out nice, so you're stuck with using technology. From my calculator I get that \theta = tan^{-1} \left ( - \frac{1}{2} \right ) \approx -26.5651^o.
