Homework Help: MATH

Posted by jennifer on Saturday, September 27, 2008 at 10:38am.

A wire is stretched from the ground to the top of an antenna tower. The wire is 20 feet long. The height of the tower is 4 feet greater than the distance from the tower's base to the end of the wire.Find the height of the tower.

20^2=H^2 + (H-4)^2
solve for h
400=2H^2 - 8H +16
H^2 - 4H-192
(H-16)(H+12) = 0
postive root h = 16 feet
tower;s base is sqrt (20^2-16^2)
=
12 feet from where the cable touches the ground

is this correct?
