Question

A helicopter makes a force landing at sea. The last
radio signal received at station C gives the bearing
of the helicopter from C as at an Ñ 57.1 degrees. É
altitude of 423 feet. An observer at C sights the
helicopter and gives <DCB as 12.1 degrees. How
far will a rescue boat at A have to travel to reach
any survivors at B? Apply the rules regarding the
use of significant digits when determining your
answer. Round your answer to the nearest ten
feet.
Distance rescue boat travels =
ft
