A helicopter makes a forced landing at sea. The last radio signal received at station C gives the bearing of the helicopter from C as at an N 57.1º E altitude of 423 feet. An observer at C sights the helicopter and gives 
as 12.1º. How far will a rescue boat at A have to travel to reach any survivors at B (see the figure)? Apply the rules regarding the use of significant digits when determining your answer. Round your answer to the nearest ten feet.
