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 Group Title

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

4. johnweldon1993 Group Title

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 Group Title

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

6. johnweldon1993 Group Title

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

7. Hope_nicole Group Title

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

8. Emily778 Group Title

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 Group Title

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

10. Hope_nicole Group Title

oh i did it backwards!

11. johnweldon1993 Group Title

:D there you go :)

12. Hope_nicole Group Title

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

13. johnweldon1993 Group Title

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 Group Title

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

15. Emily778 Group Title

thank you @johnweldon1993

16. Emily778 Group Title

The closest answer is 58. :/

17. Emily778 Group Title

For the first one

18. Emily778 Group Title

would the 2nd one be A?

19. johnweldon1993 Group Title

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

20. Emily778 Group Title

So, it is A?

21. Emily778 Group Title

@johnweldon1993

22. johnweldon1993 Group Title

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 Group Title

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 Group Title

can ya help with this?

25. johnweldon1993 Group Title

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

26. johnweldon1993 Group Title

|dw:1363206904219:dw| right?

27. Emily778 Group Title

k

28. johnweldon1993 Group Title

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

29. Emily778 Group Title

west and east

30. johnweldon1993 Group Title

|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 Group Title

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 Group Title

north and west

33. johnweldon1993 Group Title

exactly :) so...what would be your answer?

34. Emily778 Group Title

A

35. johnweldon1993 Group Title

perfect :)
