Question

in a quadilatral ABCD, angle A=150 and angle b= angle c =angle d and find angle b, angle check, angle d is.​

Answer 1

Step-by-step explanation:

in ABCD

angle A=150

angleB=C=D

let,angle B=x

B=C=D=x

angle sum of quadrilateral =360

A+B+C+D=360

150+x+x+x=360

3x=360-150

3×=210

x=210÷3

x=70

B=C=D=70
