ok

4. anonymous

angle should be easy enough to find with your eyeballs

5. anonymous

45

6. anonymous

oh no

225

if you are dealing in degrees and not radians, you can use $$-45^\circ$$ if you like

degrees but my answers are: (3 square root of 2, 315°), (-3 square root of 2, 135°) (3 square root of 2, 225°), (-3 square root of 2, 45°) (3 square root of 2, 45°), (-3 square root of 2, 225°) (3 square root of 2, 135°), (-3 square root of 2, 315°)

or if you want the positive one, use $$360-45=315$$

12. anonymous

distance is $$3\sqrt2$$ for sure

13. anonymous

ok so its the first one?

14. anonymous

so one answer could be $$(3\sqrt2,315^\circ)$$

15. anonymous

yeah go with the first one

16. anonymous

ok thanks
