The first thing we're going to do is find the solution for all solutions in degrees.
00:06
And then we're going to find, to approximate the answer to be to the nearest tenth of a degree.
00:13
So for the first one we're going to do is isolate the sine of theta.
00:17
So i'm going to subtract the one over to the other side.
00:21
And then i'm going to divide.
00:22
So i have sine theta as equal to negative 1 over 3.
00:24
Now this is not a value in the unit circle.
00:28
So we are going to have to utilize a device, a calculator, and we're having to do sign inverse of negative one -third.
00:35
So when you do it into the calculator, it's going to output a value that's going to be a negative.
00:43
Because sine inverse outputs values that go from negative 90 degrees to positive 90 degrees and everything in between...
