3 = 3x Deg,

6 = 6x Deg.

X + 3X + 6X = 180 Deg.

10X = 180,

X = 18 Deg.

3X = 3 * 18 = 54 Deg.

6X = 6 * 18 = 108 Deg.

**Reiny**, Thursday, September 30, 2010 at 5:27pmYou know their sum must add up to 180

let the angles be x, 3x and 6x

solve x + 3x + 6x = 180

sub the value of x back into the definitions
