Homework Help: geometry

Posted by Jalysa on Wednesday, October 14, 2009 at 5:47pm.

A guy wire is used to stabilize a utility pole. The wire is fastened to the pole 25 feet above the ground, and staked into the ground 4 feet from the base of the pole. (No stand-offs are used, the wire goes directly from the pole to the ground stake.) Someone recommends that more stability could be achieved by moving the ground stake out to 6 feet from the pole.

a. How long is the guy wire with the present arrangement?
b. How much longer would the guy wire have to be with the proposed arrangement?
