if someone walks 1.5 km west then 2.5 km 30 degrees south of east then 1.5 km 40 degrees north of east. Starting at the same point, what would be the angle to get someone straight from the starting point to where the other person ended??

Answer 1

break up each part of the trip into N,E components then add.

-1.5E+2.5Sin30E-2.5cos30N+1.5sin40N+1.5cos30E=final
then, after adding the N, and E components...

theta=arctan=Ncomponents/Ecomponents
