Question

In quadrilateral abcd angle d is 150 degree and what is the angle of angle a ,b and c

Answer 1

Answer:

let the angle b,c,d be x,x,x                         [as the three angles are equal]

now angle sum property of quadrilateral= 360 degree

given;angle A=150 degree

therefore,

angle A+angleB+angle C+angle D=360 degree

150+3x=360 degree

3x=210

x=70

hence, angles are

Angle A=150

Angle B=70

Angle C=70

Angle D=70 degrees
