The guy wire supporting a 100-foot tower has a tension of 520 pounds. Using the distances shown in the figure, write the component form of the vector F representing the tension in the wire. (Round
your answers to the nearest integer.)
F =

Suppose that the force acting on an object can be
expressed by the vector (85, 35, 110), where
each measure in the ordered triple represents the
force in pounds. What is the magnitude of this
force? Round your answer to two decimal
places. Show your work.
