First, note that the vector is in the 3rd quadrant, so both the x-component and the y-component will be negative.
Second, because the angle away from horizontal is less than 45°, the magnitude of the x-component is larger than the magnitude of the y-component. That suggests that the answer is A.

To calculate the actual x-component. multiply 77 times -cos(33°). It works!
