Simple Problem

Well, I've just started trig last week, and I'm having a little bit of an issue here.

Find the measure of each angle to the nearest degree.
ex. \(\displaystyle \sin(A)=.7586\)
\(\displaystyle A = 49\deg\)
(Don't know if deg means degree..)

Anyway, the problem is
\(\displaystyle \sin(A)=.8365\)
Find A

Please help me solve.

Thank you for all that contribute.

deg does mean degree.

Direct evaluation of \(\displaystyle \arcsin(0.8365)\) using a calculator should suffice.

Note that arcsin may be "inv sin" or "sin^-1" on your calculator
