Answer:
10 m due west
Explanation:
30m North
20m East
and the 30

SW can be rewritten as 30m in south and 30m in West
because south and west being at 90
0
result
in
30
2
+30
2
=30
2
so at last we have following data that in south X
S
=30m+north=30m+(−30m)=0,
negative becasue north is opposite to south.
and in West we have X
W
=30m+east=30m+(−20m)=10m
so the displacement is 10m due west
