Help me with a physics problem pleaseeeeee!!!!!?

Upon spotting an insect on a twig overhanging water, an archer fish squirts water drops at the insect to knock it into the water. Although the insect is at distance d from the fish along a straight-line path at angle φ, a drop must be launched at a different angle θ_(0) if its parabolic path is to intersect the insect. If φ = 35.0˚ and d = 0.900 m, what θ_(0) is required for the drop to be at the top of the parabolic path when it reaches the insect?
