A 135 ft tower is located on the side of a mountain that is inclined 32° to the horizontal. A guy wire is to be attached to the top of the tower and anchored at a point 55 ft downhill from the base of the tower. Find the shortest length of wire needed.
Answer by solver91311(24713) (Show Source): You can put this solution on YOUR website!
One side of your triangle is 135'. Another side is 55'. The included angle is 
. Hence, if 
is the length of the guy wire, then:
^2\ +\ (55)^2\ -\ 2(135)(55)\cos(122^\circ)})
Just do the arithmetic.
Hint:
If 
then \ <\ 0)
Since all of your given length measurements were to the nearest whole foot, the answer should also be expressed to the nearest whole foot.
