## mamma17 2 years ago 4. Find the missing value to the nearest hundredth. sin_7/12 plz help me

1. lollypopabby43

so you need to just turn it into a decimal?

2. mamma17

yeah if u need the answers i can give them to u

3. lollypopabby43

oh no i was just making sure i understood the question thanks though

4. mamma17

kk ty for helping me i am no good with math lol

5. rajathsbhat

are you allowed to use a calculator?

6. mamma17

yes

7. lollypopabby43

so if you want 7/12into a fraction just divide 7 into 12 then you have a decimal

8. mamma17

35.69° 30.26° 80.16° 54.31° thoes are the choices though

9. rajathsbhat

just plug '$$\sin(\frac{7}{12})$$' into your calculator and reduce the decimals to 2.

10. mamma17

it gives me 0.010180911

multiply that by 360 to get the degrees.

12. rajathsbhat

i wonder why the choices are in degrees....are you sure the question is written entirely and correctly?

13. rajathsbhat

@cthomasknight, why would you do that?

14. mamma17

yes i coppied it from my test itself so ik it is right

Is the question written right?

16. mamma17

yes it is

17. mamma17

it says find the missing vaule to the nearst hundredth sin_____=7/12

18. rajathsbhat

there you go. That's what we thought.

that makes much more sense. Do you know how to do it?

20. mamma17

no i suck at math

21. rajathsbhat

all you gotta do is put '$$\large \sin^{-1}(\frac{7}{12})$$' into your calc.

22. mamma17

oh ok lol

23. mamma17

so i would do the same thing with the cos______=9/20

24. rajathsbhat

yes

yes

26. mamma17
