Let the required angle be x
Then 3x + 7x + 6x + 4x = 360
20x = 360
x = 360/ 20
x = 18
3x = 3 × 18 = 54
7x = 7× 18 = 126
6x = 6× 18 = 108
4x = 4× 18 = 72
This quadrilateral is trapezium

Manyashrma: are u sure??

Abhay111111111: Because it is not a square not a rectangle so it is a trapezium

Manyashrma: ohki
