I don't know How to find a angle if the question is

arc sin(6/25)+ 90 degree

and also

arc cos (-.2065)

pls help

mmm... looks like you have no idea of what's going on, since you don't seem to know how to ask a question properly...because you question seems trivial... my guess is that you can input that into a calculator and remember to use the "degree" mode.. then you will be fine. easy

Moved from Advanced Physics to Intro Physics. rasikan, what do you know about trigonometric functions? Are you allowed to use a calculator on this problem, or are you supposed to use some other method?
