If φ = 38.0° and d = 0.900 m what θ0 is required for the drop to be at the top of the parabolic path when it reaches the insect?

Just poking at the problem I have found that the height of the insect is .55m.

If i plug the height into the max height formula, i get velocity at time 0 = 5.33m/s

I am not sure if this is even right, or if I am on the right track.
