Sarah walks 5 miles 35 degrees north of east, and then decides to walk 6 miles due west. What is her final displacement?
I drew it out, used the Pythagorean theorem and ended up with square root -11 which is obviously wrong. I'm really confused as to what to do with the angle too. I'm not sure which next steps to take.

I think it might be 5. I don't know.
