Water Tank

A water tank standing on the floor has to small holes vertically above one another punched in one side. The holes are 2cm and 8cm above the floor.

a) how high does the water stand in the tank (calculate H) when the jets from the holes hit the floor at the same point?
b)Calculate the distance x.
c) At what depth should a single hole be made to maximize x?

I think tou need to write some equations that describe the system, then solve them, so it's just cranking the handle. This is surely too complicated to do intuitively.
