<PRE><B>Question 986912</B>
A 50 foot tower is to be fastened by five guy wires attached to the top of the tower and to the ground at positions 30 feet from its base. How much wire is needed ? Round to the nearest tenth.
-------
Draw a picture of the tower, one of the wires and the 30 ft base.
You have a right triangle.
Solve for the hypotenuse::
h = sqrt(50^2+30^2) = 58.31 ft
----
Ans: Since there are 5 wires you need 5*58.31 = 291.55 ft of wire
