Dimensional Analysis And Projectile Motion Problem

1.

The work I have shown below is my attempts at doing the steps shown to get that equation in the problem, which is what the "answer" is. I need to find the work. Am I on target?

And I am totally clueless as to how I get the second answer. I know that $$\theta$$ would equal 45 degrees right? Optimal launch angle disregarding air resistance. But I'm not sure.

3. The attempt at a solution
