$\var{function_name[function_index]}(x) = \var{precround(value,4)}$
What are the possible values of x, 0≤x<360?

There's nothing more to do from here.
You are given that $\var{function_name[function_index]}(x) = \var{precround(value,4)}$.
This is positive.
cos is positive in the 1st and 4th quadrants.
The 1st quadrant angle with $\var{function_name[function_index]}(x) = \var{abs(precround(value,4))}$ is $\var{angle}$.
The corresponding 4th quadrant angle is $360 - \var{angle} = \var{quad_4}$.
