**Reiny**, Sunday, April 7, 2013 at 12:45amHere is how I do these.

First I decide in which quadrant the angles are.

Since sinx is negative, x must be in quads III or IV.

I then find the angle in standard position by finding sin^-1 (+.36) which is

.36826.. (in radians) or 21.1 degrees

so x = pi + .36826 or x = 2pi - .36826

in degrees x = 201.1 or 338.9
