Question

in a Trapezium ABCD A B parallel to CD angle A = 2x - 35 degree ,angle B equal to angle y, angle C equals to 85 degree and Angle D= 23 x + 65 degree the value of x and y are

Answer 1

2x -35 + 23x +65 = 180 (co. interior angle)

⇒ 25x +30 = 180

⇒ 25x = 150

∴ x = 6

∠ c = 85 °

∴ y = 180 - 85 = 95 °(co. interior angle).
