hint ...we have an angle....and we have sides opposite to that angle...and the hypotenuse correct? what trig function uses opposite and hypotenuse?

3. Hope_nicole

you can use the trig function sin.

4. johnweldon1993

exactly as @Hope_nicole has said....sin is opposite/hypotenus correct? so we have sin(x) = 11/17 we dont know x right? so we need to use the inverse sin to find this answer $\sin^{-1} 11/17$ this will give you your x...just do 11/17...then inverse sin...of that answer

5. Hope_nicole

yupp @johnweldon1993

6. johnweldon1993

do you understand the method behind that @Emily778 ?

7. Emily778

How do I inverse the sin?

8. johnweldon1993

you have a calculator correct? instead of just hitting sin...hit "2nd" (probably a blue or yellow button in the top left hand side" then hit sin...that should be sin^-1

9. Hope_nicole

you hit the second button your calculator and then hit the sin button.

10. johnweldon1993

*****************remember to have your calculator in DEGREES mode and not RADIANS mode*********** :) that's a VERY common mistake

11. Hope_nicole

^i do that so much!

12. Emily778

I don't know how to get it in degrees and I can't find the 2nd button

13. Hope_nicole

the second button is going to be in the very top on the left.

14. Emily778

there's shift, const, eng, mode, copy, and off at the top. No 2nd

15. Hope_nicole

then it would be shift, right @johnweldon1993

16. johnweldon1993

yeah shift would be correct

17. johnweldon1993

so shift...then sin...you should see $\sin^{-1}$ pop up

18. Emily778

okay, shift sin and then 11/17?

19. Hope_nicole

yes

20. Emily778

um, I got 5.29 and then -10 ?

21. johnweldon1993

.....do 11/17 first thennnn do "shift" "sin" and then put the answer from 11/17 in there

22. Emily778

Is this some kind of joke? I'm not getting any answer...-_-

23. Hope_nicole

do 11/17 and then hit shift sin

24. Hope_nicole

my calculator does it that way

25. johnweldon1993

....what calculator do you have? lol okay...well for me $\sin^{-1} 11/17$ comes out to 40 degrees...if you can figure out your calculators method to doing this lol....then awesome haha

26. johnweldon1993

try @Hope_nicole 's method

27. Hope_nicole

yes, try doing 11/17, hitting the equal button and then hitting shift sin

28. Emily778

I did...

29. Emily778

Thanks, @johnweldon1993 and I have a online graphing calculator.

30. Emily778

31. johnweldon1993

:) did you figure out that calculator though? if not...i HIGHLY recommend getting a calculator...as you can see...they will come in handy
