Draw a diagonal in the quadrilateral which divide tha quadrilateral in two triangles since sum of angles of triangle is 180 so sum of the angles of the two triangles will be 180+180=360

let the ratio be 4x :6x: 3x:5x
sum of angles of quadrilateral is 360
so 4x+6x+3x+5x=360
18x=360
x=360÷18
x=20
thus measure of angles are
4x=80
6x=120
3x=60
5x=100
