Subject: Crossed Ladders Problem (again)
L.A. Graham, in the Dover book "Ingenious Mathematical Problems and

Methods" on page 18, Problem 25 "The Two Ladders", presents the classic

problem of two ladders, one 20 ft. long, the other 30 ft. long, each

crossing each other 8 ft. above the floor, and the question is asked "How

wide is the room?

Is there anyway to solve this problem, without resorting to a quartic

equation, and using Ferrari's method?

Thanks for your input.
