**Solving Cyclic Quadrilaterals TutorVista**

In cyclic quadrilateral opposite angles sum is equal to 180° So Angle A + Angle C = 180° => 2x-1 + 2y+15 = 180° => x+y = 83° eqn.1 and similarly Angle B + Angle D = 180°... The opposite angles of a cyclic quadrilateral are supplementary. (Reason: opp. s cyclic quad.) Circle with centre with points and on the circumference such that is a cyclic quadrilateral.
