I am working on a statics question and one of the angles is sin^-1(0.750) which I calculate as 48.6 degrees though the book gives 131.41 degrees
If I calculate sin(48.6) it equals 0.750
If I calculate sin(131.41) it equals 0.750
Clearly there is some relation or rule that I am unaware of. How do I ensure that I find the proper angle?
