# Simple Problem

#### Tyman2007

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

Thank you for all that contribute.

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
