Question 818450
x = largest angle
x - 10 = medium angle
x - 50 = smallest angle


x + x - 10 + x - 50 = 180 {angles of a triangle add up to 180°}
3x - 60 = 180 {combined like terms}
3x = 240 {added 60 to each side}
x = 80 {divided each side by 4}
x - 10 = 70 {substituted 80, in for x, into x - 10}
x - 50 = 30 {substituted 80, in for x, into x - 50}


80°, 70°, and 30° are the measures of the angles
