    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. \sin(A)=.7586
    A = 49\deg
    (Don't know if deg means degree..)

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

    Please help me solve.

    Thank you for all that contribute.

    deg does mean degree.

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

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