Answer:

weather you can check in u tube because

Explanation:

here u cant understand

Answer 2

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

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
