the question is " A wind with a velocity of 40.3 KM/H blows [E22.3 N]. What is the north component of the velocity in Km/h?

I know how to solve it but wondering which graph I am supposed to use to determine my answer. Is it 40.3sin22.3 or 40.3sin22.3

Thanks in advance

No. It means 22.3 degrees north of east. Picture your boat heading east (the initial direction mentioned), then turning 22.3 degrees toward north. So use the sine.
