Which is the correct answer? The one on the sheet of paper or the calculator?

If you don't know, it should tell you what mode to be working in or you should get a clue in the question.

You should be in radian mode, and I get 1.7607 on the calculator doing 20 x ((sin20)/10.37)
is this what you meant?
or 20 x (sin (20/10.37))
?
How are you working it out on paper?

Check your mode. Your calculator may be in radian/degree mode without you realising Change it to the other and see if it works

To get 0.659 you need to be in degree mode. On my calculator (casio) that means pressing mode twice, and then 1.
