    any chance of solving for theta_g?

    Any chance of solving for \theta_\gamma?

    x=\sqrt{\frac{b^2\sin^2\theta_\gamma+\cos^2\theta_  \gamma}{\tan^2\theta_\gamma+1}}

    Start with the fact that \tan^2\theta_\gamma+1 = \sec^2\theta_\gamma = 1/\cos^2\theta_\gamma. So x = \sqrt{(b^2\sin^2\theta_\gamma+\cos^2\theta_\gamma) \cos^2\theta_\gamma}. Square both sides, replace \sin^2\theta_\gamma by 1-\cos^2\theta_\gamma, and you have a quadratic equation for \cos^2\theta_\gamma.
