The Coast Guard has sent a rescue helicopter to retrieve passengers off a disabled ship. The ship has called in its
position as 1.7 miles from shore. When the helicopter
passes over a buoy that is known to be 1.3 miles from
shore, the angle formed by the shore, the helicopter,
and the disabled ship is 90°. Determine what
the altimeter would read to the nearest foot
when the helicopter is directly above the buoy.
