Chapter 9 Review Geometry

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 1.3 miles from shore. The angle formed by the shore, the helicopter and the disabled ship is 90 degrees. How high is the helicopter above the buoy to the nearest foot.

(1 mile = 5280 feet)
