 In the given figure, $\mathrm{PQL}$ and $\mathrm{PRM}$ are two tangents to the circle with centre $\mathrm{O}$ at the point $\mathrm{Q}$and $\mathrm{R}$ respectively. If $\mathrm{S}$ is a point on the circle such that angle $\mathrm{SQL} = 50°$and angle $\mathrm{SRM} = 60°.$ Find the reflex angle $\mathrm{QOR}.$
