North, East, South, West airplane thingy
Hi, thank you (again?) for taking the time to look at my problem.
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 N 57.1degrees E at an 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 sgnificant digits when determining your answer.
I redid the figure on paint. The helicopter pictures are at D and B.
How should I do this?
