What do you think the answer is? :o

2. anonymous

I'd love to tell you, if I had any idea.

Ok let's plot $$(3,-3)$$;|dw:1435770062478:dw| We know length is $$3\sqrt2$$ (all choice has that length) So about angle...

4. geerky42

|dw:1435770186673:dw| Can you determine angle for green arrow one?

5. anonymous

Since 360 - 45 = 315, would that be the green angle?

6. Loser66

|dw:1435771341338:dw| the length of the side is $$3\sqrt 2$$ right? and the direction of the side is positive, hence, $$3\sqrt 2, 315$$ is one of the answer.

7. Loser66

Fortunately, you have only 1 option which has that part. If the first part of the option is correct, so as the second one, right?

8. Loser66

I cheat !! hehehe.. but if it works, why not? As long as the first logic ok, I am ok.

9. anonymous

Makes sense, but then comes me wondering how you got 45 degrees out of that angle. Was it guessing?

10. Loser66

|dw:1435771659679:dw|

11. Loser66

that gives you -45 degree. This time, I don't cheat. hehehe

12. anonymous

Ah, I understand now. Thank you.

13. Loser66

ok
