**drwls**, Saturday, September 18, 2010 at 6:24pmLet L be the distance between cliffs and y be the height where the cables intersect, x is the horizontal distance from the lower cliff to below the intersection point.

y/x = 600/L

y/(L-x) = 400/L

(L-x)/y * (y/x) = 600/400 = 3/2

(L-x)/x = 3/2

L/x -1 = 3/2

L/x = 5/2

x/L = 2/5

y = (x/L)*600 = 240 m

You will have to draw your own figure.
