Step-by-step explanation:
ratio of angles of quadrilateral = 3 : 4 : 5 : 6
let the angles of a quadri be = 3x ,4x ,5x ,6x
sum of quadrilateral = 360°
3x + 4x + 5x + 6x = 360°
18x = 360°
x = 360/18
x = 20
angles of quadrilaterals = 3x = 3×20 = 60°
= 4x = 4×20 = 80°
= 5x = 5×20 = 100°
= 6x = 6×20 = 120°
i hope it helps you ✌️✌️
