Question 160779
Not quite
The first angle is 3 times the second. You have the second angle as 3 times the first. 
Likewise, the first angle is 6 times the third. You have the thrid angle as 6 times the first.

The angles should be {{{x , x/3, x/6}}}
You know the sum of the angles is 180 (since this is a triangle)
{{{180 = x + x/3 + x/6}}}
{{{180 = (6x + 2x + x)/6}}}
{{{1080 = 9x}}}
{{{120 = x}}}}
So the other angles are 120/3 = 40
and 120/6 = 20

Does 120+40+20 = 180?
