Question

In a Quadrilateral ABCD. /_ D=150° /_A,/_B /_C . Find the measures of /_A,/_B,/_C​

Answer 1

hi mate pls mark me as branliest

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 150,70,70 and 70 degrees

Answer 2

Step-by-step explanation:

x=70 degree
