order of operations when using sin()?

Question

trying to solve this example: 10·sin(50)/sin(110)

and wolfram says its 8.15. if i enter it the same way into google calculator, it says its 59.

and my own calculator says 7.15. it also says sin of 50 is 0.7, then google says sin of 50 is -0.2.

so i have no clue. how do i even solve this?

Make sure you’re consistent with units. One might be using degrees to measure angles, whereas one might be using radians, or even steradians!
