A wooden board is placed so that it leans against a loading dock to provide a ramp.
The board is supported by a metal beam perpendicular to the ramp and placed on a 1 ft. tall support.
The bottom of the support is 7 feet from the point where the ramp meets the ground. The slope of the ramp is 2/5.
Find the length of the beam to the nearest hundredth of a foot. Note that the 1 ft. support is vertical, but the metal beam is not.
Thanks,
ME
