Best ResponseYou've already chosen the best response.0In other words:\[\sin x = \frac{ 6 }{ 45 }\]

Best ResponseYou've already chosen the best response.0sines go with the angle. Arcsines (inverse sines) go with the ratio of the sides.

Best ResponseYou've already chosen the best response.0So, to calculate that, you set your calculator to "degrees", type in 6/45, then hit inverse sine.

Best ResponseYou've already chosen the best response.0It will give back the angle whose sine is 6/45. Good luck in all of your studies and thx for the recognition! @mattishot
