The equation sin(x) + 2 = 1 can be rearranged as sin(x) = -1.

However, the range of sine function is -1 to 1. Since there is no angle whose sine value is greater than 1 or less than -1, this equation has no solution in real numbers.

Therefore, none of the provided answer choices (270 degrees, 180 degrees, 60 degrees and 30 degrees) are solutions to the given equation.
