Traversing is carried out for a closed traverse $\text{PQRS}$. The internal angles at vertices $\text{P, Q, R and S}$ are measured as $92^{\circ},68^{\circ},123^{\circ}$ and $77^{\circ}$, respectively. If fore bearing of line $\text{PQ}$ is $27^{\circ}$, fore bearing of line $\text{RS}$ (in degrees, in integer) is ___________________
