\theta=30,210,150,330θ=30,210,150,330

Explanation:

tan^{2}\theta = \frac{1}{3}tan2θ=13

Therefore:

tan\theta=+-\frac{1}{\sqrt{3}}tanθ=±13

Solutions cna be found such that:

\theta=tan^{-1}(\frac{1}{\sqrt{3}})=30, 210θ=tan1(13)=30,210 Using the 180 cycle in a tan graph.

doing the same for the negation version gives us:
\theta=tan^{-1}(-\frac{1}{\sqrt{3}})=cancel(-30),150,330

therefore all the solutions are:
\theta=30,210,150,330
