Explanation:
If PQRS is a quadrilateral inscribed in a circle, then the opposite angles of the quadrilateral are supplementary.
y + 68° = 180° { being opposite angles of cyclic quadrilateral }
y = 180° - 68°
y = 112°
x + 82° = 180° { being opposite angles of cyclic quadrilateral }
x = 180° - 82°
x = 98°
