The screen shot of the question is attached, this is apparently a basic trig question but it doesn't feel that way. Please explain as much as possible! Thanks!

Homework questions should be posted in the appropriate homework forum. Follow the template there and make sure you explain where you need help at. That way you can get the best help possible!
 
You don't need any trig, just algebra. Follow Drakkith's suggestion if you still need help.
 
Do they do vectors in algebra? I don't remember that.

you don't need vectors or trig, just algebra. You're given the coordinates of two points and asked to find the distance between them. That's just algebra

Ah, ok. I just glanced at it and saw vectors.
