A 10ft pole is to be erected and held in the ground by four wires attached at the top. The guy wires are attached to the ground
ad-work [718]
The pole, guy wire and ground forms a right angled triangle with the guy wire being the hypotenuse.
Legs = 10 ft and 15 ft.

The length of guys wire = Sqrt (10^2+15^2) = 5 \sqrt{13} ≈18.03 ft

A total of 4 guy wires.
Te total length required = 4*5\sqrt{13} ≈ 72.11 ft.

Since wire cannot be bought in fractions of foot, the length is rounded to the next whole number. That is,

Length required = 73 ft.
