If a pair of opposite angles of a quadrilateral is supplementary, then the quadrilateral is quadrilateral

In figure $PQ$, is a chord of a circle with centre $O$ and $PT$ is its tangent at $P$. if $\angle QPT=60°$, then $\angle PRQ$ is

In the figure, points $P,Q,R$ and $S$ lie on a circle. Then the values of $x$ and $y$ are respectively

The sum of pairs of opposite angles of a cyclic quadrilateral is
