The set is the set of all values of
that are solutions to the given equation. So all you need to do is check whether
and
satisfy the equation.
The equation holds, so both 1 and 2 are solutions, and hence is a subset of the solutions.

Answer:
C
Step-by-step explanation:
Coterminal angles are angles that have a common terminal side.
So, given an angle θ, its coterminal angles will always be ±360°. This can be repeated.
We have a 645° angle.
Therefore, all values of the equation:
Where <em>n</em> is an integer is coterminal with our original angle.
Letting <em>n</em> = 1 and using the negative case, we acquire:
Therefore, an angle measuring 285° is coterminal with a 645° angle.
None of the other options can be reached by adding/subtracting 360.
Therefore, our answer is C.
