I'm just starting out physics and I'm currently trying to do vector equations. I actually have a question about a couple of problems.(adsbygoogle = window.adsbygoogle || []).push({});

The first is a plane flies 55 degrees northeast for 243km. How far north did the plane fly north? How far east did the plane fly?

I started out making a triangle, with the hypotenuse being 243 km and the angle as 55 degrees. I thought I could use sin and cos to figure out the two missing sides, but I'm not sure how to apply the degree with one side length...

I did sin(55)=a/243 but I'm not sure where to go from here.

My second question is a flight of geese fly at 72 degrees southwest at 23km/hr for winter. With what speed were the geese flying south? With what velocity were the geese flying west?

Once again, I made a triangle with 72 as the degree and 23 km/hr for the hypotenuse. I think my problem is the same as the first. Not knowing how to get the missing side length.
