 (((25cos 210°)),((25sin 210°)) )= (((−((25(√3))/2))),((−((25)/2))) ) ≈ (((−21.6506)),((−12.5)) )
$$\begin{pmatrix}{\mathrm{25cos}\:\mathrm{210}°}\\{\mathrm{25sin}\:\mathrm{210}°}\end{pmatrix}=\begin{pmatrix}{−\frac{\mathrm{25}\sqrt{\mathrm{3}}}{\mathrm{2}}}\\{−\frac{\mathrm{25}}{\mathrm{2}}}\end{pmatrix}\:\approx\begin{pmatrix}{−\mathrm{21}.\mathrm{6506}}\\{−\mathrm{12}.\mathrm{5}}\end{pmatrix} \\ $$

I guess no. if you use the absolute values  the angle changes to 30°
$$\mathrm{I}\:\mathrm{guess}\:\mathrm{no}.\:\mathrm{if}\:\mathrm{you}\:\mathrm{use}\:\mathrm{the}\:\mathrm{absolute}\:\mathrm{values} \\ $$$$\mathrm{the}\:\mathrm{angle}\:\mathrm{changes}\:\mathrm{to}\:\mathrm{30}° \\ $$
