Vector addition car problem

A car is driven 215 km west and then 85 km southwest. What is the displacement of the car from the point of origin?

Shouldn't I be given an angle. Because it could be southwest at any angle. How would I do this?

Thanks for the help.

Southwest usually means 45 degrees towards south, from west or vice-versa.

Really? Okay let me try that. But why would I be expected to know that? That's just stupid.

Take a look at a compass and see why ;)

It's just convention when mentioning southwest that the angle is 45 degrees. It is also true when saying southeast, northeast, northwest.
