You convert by adding the equivalent of a circle, either 360 degrees or 2 pi radians.

So converting - 0.848 radians to positive radian measure gives you what?

And 2A equals that number so A equals?

Now, when I explained about the arcsin, I said that it had a limited domain. It only gives answers for angles in the first and fourth quadrant. In what quadrants is the sine function negative and so possibly equal to - 0.75?
