Because the two angles on the right add to 180 degrees, we can create this system:
We can also prove that
, which, when solved, shows that
.
When plugged in to the original equation, we find that y = 105 degrees.
The center of the circle is (0,-4) and the radius is 8 because the center comes from the (x-_) and (y-_) and the radius is square root the =_
20*5 = 100.
You can check with your calculator.
