(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

theta = tan^-1 {{v^2 - [v^4-g(gx^2)]}^1/2}/gx

I know that x is 30, theta is 45, g is 9.81 m/sec^2.

I'm trying to solve for v.

2. Relevant equations

3. The attempt at a solution

I've gotten all the way down to

v^2 = (v^4-86612.49)^1/2 + 4.165

What do I do from here?
