trig: find (theta) if sin (theta)=-.3030 and (theta) is in Q

[nobodybutjustme]

I need help remembering how to do this type of problem:

Find (theta) if sin(theta) = -0.3030 and (theta) is in Quadrant III.

Do we get to use a calculator? Use the inverse sine function. This should give you an answer in Quadrant IV. Subtract that value from pi and you're in business.
