villages A;B;C;D are such that B is 4km due east of A ;C is 3km due south of B and D is 4km S50w from C.Calculate the distance and bearing of A from D.

1 answer

with A at (0,0) we just add the x- and y-displacements to get the final location:

<4,0>+<0,-3>+<-3.06,-2.57> = <0.94,-5.57>

Now you can find the distance and bearing.
