Question

Suppose you first walk 12.0 m in a direction 20º west of
north and then 20.0 m in a direction 40.0º south of west.
How far are you from your starting point, and what is the
compass direction of a line connecting your starting point to
your final position? (If you represent the two legs of the walk
as vector displacements A and B , then
this problem finds their sum R = A + B .)
