Your friend went on a trip to
Kennywood Park. While there,
he examined the inclined section
of the roller-coaster track for the
Phantom's Revenge. He noticed
the ramp section rose at a
45° angle with the horizontal
section, and connected at the top
of the hill with a segment 100 feet
long. These pieces formed a right
angle at the top of the hill. Find x,
the length from the point of inclination
to the bottom of the hill.
