Let the ratio of triangle be X
Then side 2x..... 6X....... And7x
But the sum of all angle of triangle=180°
So, <A+<B<C=180°
2X+6X+7X=180°
15x=180°
X=12°
Now smallest complement is 2*12=24°
Then side 2x..... 6X....... And7x
But the sum of all angle of triangle=180°
So, <A+<B<C=180°
2X+6X+7X=180°
15x=180°
X=12°
Now smallest complement is 2*12=24°
