A firefighter a distance d from a burning building directs a stream of water from a fire hose at angle θi above the horizontal as in the figure. If the initial speed of the stream is vi, at what height h does the water strike the building? (Use theta for θi, vi for vi, g for acceleration due to gravity, and d and h as necessary.)

What i have with me is

vi*sin(theta) - (g*sqrt(2*h/g))

however it is not correct.
