Let $P Q R S$ be a quadrilateral in a plane, where
$Q R=1, \angle P Q R=\angle Q R S=70^{\circ}, \angle P Q S=15^{\circ}$ and $\angle P R S=40^{\circ}$.
If $\angle R P S=\theta^{\circ}, P Q=\alpha$ and $P S=\beta$, then the interval(s) that contain(s) the value of
$4 \alpha \beta \sin \theta^{\circ}$ is/are
