Question

in a quadrilateral ABCD angle b is equal to 150 degree and Angle is what Angle B equal to angle c equal find angle A and Angle B and angle C​

Answer 1

Answer:

∠D = 150°

Let∠A =∠B =∠C = x

By angle sum property of quadrilateral,

∠A + ∠B + ∠C +∠D = 360°

x + x +x+∠D = 360°

3x+∠D = 360°

3x = 360°–∠D

30 = 360° – 150°

3x = 210°

x = 70°

Hence,∠A =∠B =∠C = 70°.
