Answer:
Step-by-step explanation:
a circle will satisfy the conditions of Green's Theorem since it is closed and simple.
Let's identify P and Q from the integral
, and
Now, using Green's theorem on the line integral gives,

If a number equals the same number, there are infinite solutions
Example: 5=5, which is true, so there are infinite solutions
If a number equals a different number, there are no solutions
Example: 5=2, which isn’t true
The first two is wrong, the last two is one of the right ones, I think it’s c
The correct answer for x would be 36 or 36°
