We know that the sum of all angles of quadrilateral is 360 so let the 4 angles be a,b,c,d and according to question, a=b=c =x(let) Now, a+b+c+d=360 x+x+x+144=360 3x=360-144 3x=216 x=216/3 x=72 So rest 3 angles are 72°

Given three angles of a quadrilateral are equal
let the angle be x⁰
fourth angle = 144⁰
sum of four angles of quadrilateral = 360⁰
x⁰ + x⁰ + x⁰ +144⁰ = 360⁰
3x⁰ = 360 - 144
x⁰ = 72⁰
