Segments $AD=15$, $BE=8$, $CF=30$ are drawn from the vertices of triangle $ABC$, each perpendicular to a straight line $RS$, which does not intersect the triangle. Points $D$, $E$, $F$ are the intersection points of $RS$ with the perpendiculars. Given that $A$, $B$, and $C$ are the vertices of triangle $ABC$, calculate the length of the perpendicular segment $GH$ from the centroid $G$ of the triangle to the line $RS$.
