30m North
20m East
and the 30√2 SW can be rewritten as 30m in south and 30m in West
because south and west being at 900 result
in √302+302=30√2
so at last we have following data that in south XS=30m+north=30m+(−30m)=0,
negative becasue north is opposite to south.
and in West we have XW=30m+east=30m+(−20m)=10m
so the displacement is 10m due west
