Actually, 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.

In other words:\[\sin x = \frac{ 6 }{ 45 }\]

\[x = \sin^{1} \frac{ 6 }{ 45 }\]

sines go with the angle. Arcsines (inverse sines) go with the ratio of the sides.

So, to calculate that, you set your calculator to "degrees", type in 6/45, then hit inverse sine.

It will give back the angle whose sine is 6/45. Good luck in all of your studies and thx for the recognition! @mattishot
