## anonymous one year ago i need help finding the value of x in a 90 degree triangle with sides 11 and 6

• This Question is Open
1. anonymous

so 73 ? but i need to find both angles

2. nikato

do you have a diagram? what is x? are you solving for angles or sides?

3. lizz123

Is there a picture?

4. anonymous

|dw:1433203333641:dw|

5. anonymous

it says find the value of x

6. anonymous

i think its 60 because of the 30 60 90 triangle rule

7. anonymous

??????

8. nikato

i dont think you can tell its a 30-60-90 trianlge. i think you should use trig do you know SOHCAHTOA?

9. anonymous

no

10. nikato

ok. what are you learning in class now?

11. anonymous

im working on a final exam review sheet

12. nikato

oh, so you've never learned about cos, sin, and tan?

13. anonymous

yes i just dont remeber

14. anonymous

???

15. nikato

|dw:1433204161087:dw|

16. nikato

does this look familiar?

17. anonymous

yes but i dont have the opposite side to plug into the formulaa

18. nikato

|dw:1433204311868:dw| you are given the opp. and adj sides

19. anonymous

i was looking at the wrong one srry

20. nikato

and if you remember SOHCAHTOA |dw:1433204373435:dw| these are the ratios

21. anonymous

now i have tan 11/6 so do i just divide or leave it

22. nikato

actually |dw:1433204573177:dw|

23. anonymous

24. nikato

so |dw:1433204615277:dw| thsi is what you would put into your calculator to solve for theta or the angle

25. nikato

26. anonymous

can you solve it i dont have a scientific calc with me

27. nikato

online calculator?

28. anonymous

where

29. nikato

just google and a few will pop up but i got around 61.39

30. anonymous

31. anonymous

?

32. nikato

|dw:1433204934476:dw| no. its like a function. you will put that in your calculator

33. anonymous

ok. can you answer another one

34. nikato

sure

35. anonymous

find the value of the variables if your answer is not an iteger leave it in simplesty form

36. anonymous

|dw:1433205052602:dw|

37. anonymous

sorry that says 30 degrees

38. anonymous

39. nikato

so this is a 30-60-90 triangle

40. anonymous

yes

41. anonymous

do we use a trig ratio for this one?

42. nikato

you can use it if you want

43. nikato

|dw:1433205512354:dw| or you can remember this ratio only for 30-60-90 triangles

44. anonymous

but how if i only have one side

45. nikato

nvm the ratio thing doesnt work for your triangle. its weird

46. nikato

|dw:1433205641855:dw|

47. nikato

so ypu have |dw:1433205684313:dw|
