let x be the angle

let x be the angle the sum of three angle = 180*

let x be the angle the sum of three angle = 180* 1x + 2x + 6x = 180

let x be the angle the sum of three angle = 180* 1x + 2x + 6x = 180

9x=180

9x=180

x=180/9

x=180/9

x=20

the three angle

1x=1×20 =20*

2x=2×20 =40*

6x=6×20 =120*
