A function g x x has x-intercepts at 1/2 + 0 + 6 + 0 which could g x x

The angles in a triangle always add to 180°.therefore: (2x) + (2x + 9) + (3x - 11) = 1802x + 2x + 9 + 3x - 11 = 180(2x + 2x + 3x) + (9 - 11) = 1807x - 2 = 180    |+27x = 182    |: 7x = 262x = 2 · 26 = 522x + 9 = 2 · 26 + 9 = 613x - 11 = 3 · 26 - 11 = 67answer: the measure of the smallest angle is 52°.
