Question 945510
x = one angle
2x - 45 = other angle  {one angle is 45 less than twice its supplement}


x + 2x - 45 = 180   {supplementary angles add up to 180°}
3x - 45 = 180  {combined like terms}
3x = 225 {added 45 to each side}
x = 75   {divided each side by 3}
2x - 45 = 105 {substituted 75, in for x,into 2x - 45}


75° and 105° are the two supplementary angles
