Triangles $\triangle DEF$ and $\triangle D'E'F'$ are positioned in the coordinate plane with vertices $D(0,0)$, $E(0,10)$, $F(14,0)$, $D'(20,20)$, $E'(30,20)$, $F'(20,8)$. Determine the angle of rotation $n$ degrees clockwise around the point $(p,q)$ where $0<n<180$, that transforms $\triangle DEF$ to $\triangle D'E'F'$. Find $n+p+q$.
