Yes indeed! How perceptive of you, Dru!
But I would posit that Plaidman was actually wondering "how far out from the wall would I be" if I were at the end of a 200-foot rope on a 110 degree overhanging wall. While his actual distance from the wall (at his closest approach) would be 68.4 feet as you so aptly demonstrate, he prolly was looking for the horizontal distance from the wall. Only Plaidman knows...
What say ye all to a 4th page? I still have more Fat Tires here...
