Answer:
x=20
Step-by-step explanation:
sum of all angles of a quadrilateral is 360
3x + 4x + 5x + 6x = 360
18x=360
x=20
so,
3x=3 x 20= 60
4x=4 x 20= 80
5x=5 x 20=100
6x= 6 x 20=120

Answer:
Sum of angles of quadrilateral = 360
3x + 4x+ 5x + 6x = 360
18x = 360
x= 360 / 18
x=20
1st angle = 20 x 3 = 60
2nd angle = 20 x 4 = 80
3rd angle = 20 x 5 = 100
4th angle = 20 x 6 = 120
