<PRE><B>Question 1027141</B>
 A straight, tight wire is stretched from the top of a vertical pole to a point on the ground which is 9 ft away from the base of the pole. If the wire is 13 ft in length, what is the exact height of the pole? 
----
Sketch the figure::
wire = hypotenuse = 13 ft
base = 9 ft
------
h^2 = 13^2 - 9^2 = 169-81
h = sqrt(87) = 9.33 ft
