Best ResponseYou've already chosen the best response.1Actually, the angle is the arcsin 6/45. It's the inverse sine. You are given the sine. It's the angle is what you are looking for.

Best ResponseYou've already chosen the best response.1In other words:\[\sin x = \frac{ 6 }{ 45 }\]

Best ResponseYou've already chosen the best response.1sines go with the angle. Arcsines (inverse sines) go with the ratio of the sides.

Best ResponseYou've already chosen the best response.1So, 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.1It will give back the angle whose sine is 6/45. Good luck in all of your studies and thx for the recognition! @mattishot
