**MathMate**, Wednesday, January 26, 2011 at 7:50amUse Pythagoras theorem,

L = √(H²+D²)

or

L² = H²+D²

L=Length of the rope = 120'

D=Depth = 20'

H=Horizontal distance of the anchor from the boat

From

L² = H²+D²

we get

H² = L² - D²

= 120²-20²

=14400 - 400

= 14000

Horizontal distance

= √H

= 118.3'
