**Reiny**, Friday, June 15, 2012 at 11:45pmUsing similar triangles and ratios, we can find the height of the tower.

h/60 = 3/2

h = 90

then by Pythagoras:

let the length of the wire be x

x^2 = 60^2+90^2

x = √11700 = appr 108.2 ft

or

using trig, let the angle formed by Ø

tanØ = 3/2

Ø = 56.31°

then cosØ = 60/x

x = 60/cos 56.31° = 108.2
