WebJul 4, 2024 · The angles of a cyclic quadrilateral are. ∠A = 2x + 4 = 66 + 4 = 70 o. ∠B = y + 3 = 50 + 3 = 53 o. ∠C = 2y + 10 = 100 + 10 = 110 o. ∠D = 4x – 5 = 132 – 5 = 127 o. Hence, the … WebMar 8, 2015 · 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, 3x = 99 deg; x= 33 deg y = 50 deg. now calculate A,B,C and D.
