Question 486612
Let {{{x}}} degrees is the smallest angle
then other angles are {{{5x}}} and {{{6x}}} degrees
The sum of angles in triangle is 180 degrees
{{{x+5x+6x=180}}}
{{{12x=180}}}
{{{x=180/12}}}
{{{x=15}}}degrees is the smallest angle
The other angles are {{{5*15=75}}} degrees, {{{6*15=90}}} degrees
