WebGiven: In a cyclic quadrilateral ABCD, $\angle A = (2x+ 4)^o, \angle B = (y + 3)^o, \angle C = (2y+10)^o$ and $\angle D = (4x - 5)^o$. To do: We have to find the four ... WebGaurav Seth 4 years, 1 month ago. In a cyclic quadrilateral, Opposite angles are supplementary. angle A + angle C = 180 deg. and also angle B + angle D = 180 deg. Now 2x + 4 + 2y + 10 = 180 => x+y = 83 deg. similarly, y+3+4x-5 = 180 => 4x+y = 182 deg. solving the two simultaneous equations in x and y we get,
