Question

the quadrilateral ABCD angle A 150 degree and Angle B is equal angle C is equal angle D find the angle B, angle C and angle D
​

Answer 1

Answer:

ans is 70°

as angle b,c,d are equal let them be x

so angle a+b+c+d=360

angle a=150

so 150+x+x+x=360°

3x=360-150°

3x=210°

x=210/3

x=70°
