same thing here :) we have an angle...and we have sides adjacent to...and opposite of that angle...what trig function uses adjacent and opposite ?

3. Emily778

It always gives me a stupid answer on this calculator...

4. johnweldon1993

lol...ugh need to figure that out lol....okay well what did you put in (what trig function) (x) of what / what?

5. Hope_nicole

it should be around 32.27 you would use tangent for this one.

6. johnweldon1993

-_- @Hope_nicole lol i was making sure she knew what trig function to use :P

7. Hope_nicole

well...@Emily778 always remember SOH CAH TOA!

8. Emily778

Thanks @Hope_nicole could you guys help out with this one? . Describe the vector as an ordered pair. Round the coordinates to the nearest tenth. The figure is not drawn to scale. (1 point) (19.4, 50.4) (50.4, 19.4) (19.4, 19.4) (50.4, 50.4)

9. johnweldon1993

and @Hope_nicole ...32.27?? tan is opposite / adjacent right?

10. Hope_nicole

oh i did it backwards!

11. johnweldon1993

:D there you go :)

12. Hope_nicole

oh vectors are not my thing, my teacher skipped our unit on them :/ sorry!

13. johnweldon1993

lol...hmm vectors let me remember physics okay ...you want the x-component...and the y-component to do this you take the magnitude (the length of the line) and multiply it by either cos(angle) or sin (angle) cos is the x-component (in the x direction) sin is the y-component (in the y direction) so 54cos(69) =? 54sin(69) =?

14. johnweldon1993

and @Emily778 ..the answer for the first question you originally asked ...is 57.72

15. Emily778

thank you @johnweldon1993

16. Emily778

The closest answer is 58. :/

17. Emily778

For the first one

18. Emily778

would the 2nd one be A?

19. johnweldon1993

sorry about the late reply...alright 54cos(69) = 19.35 54sin(69) = 50.41 lol you must HATE that calculator

20. Emily778

So, it is A?

21. Emily778

@johnweldon1993

22. johnweldon1993

correct :)...because like i said...cos is in the x direction...(a.k.a your x value) and sin is in the y direction (your y value) so since a coordinate looks like (x,y) you use the cos answer , sin answer so yes...A :)

23. Emily778

Use compass directions to describe the direction of the vector. (1 point) 41 west of north 41 east of south 41 west of south 41 east of north

24. Emily778

can ya help with this?

25. johnweldon1993

absolutely...so imagine a compass....we have

26. johnweldon1993

|dw:1363206904219:dw| right?

27. Emily778

k

28. johnweldon1993

so that is a compass....the line we have....looks like it is between which 2 directions?

29. Emily778

west and east

30. johnweldon1993

|dw:1363207318614:dw| that is our line and we have put it on our compass.. so. N=north W=west S=south E=east right? so since the line goes inbetween N and W right? so what 2 directions?

31. johnweldon1993

see what i mean by that? |dw:1363207479263:dw| it is inbetween those 2 areas right? that's inbetween N and W which is?

32. Emily778

north and west
