Moderately hard geometry problem.. (3 step minimum)
Hello, I need a lot of help with this one because I can't seem to find any way to complete it.(Wait) It's not a matter of the calculations, (I can do those just fine) but a matter of which step to do and for what. There should be at least 3 steps. Thanks for your help!(Nod)

A wooden board is placed so that it leans against a loading dock to provide a ramp. The board is supported by a metal beam perpendicular to the ramp and placed on a 1 ft. tall support. The bottom of the support is 8 feet from the point where the ramp meets the ground. The slope of the ramp is 2/5 (this means that for every 2 feet it goes up, it goes 5 to the side). Find the length of the beam to the nearest hundredth of a foot. Note that the 1 ft. support is vertical, but the metal beam is not

I solved this problem a short while ago here. (In fact, if you look, I solved it in two different ways - take your pick!)
