    This would look like a right angle but not so im guessing it would be a obtuse triangle thing (if that is even possible).

    we i would say if u add 71 , 28, and 43 all together it would make 180 but it makes 142 :/

    sum = 180 so x + 109 + 28 = 180 find x

    180- 28 = 152 but that wouldnt be x it would not make sense

    so to review angles on a straight line add up to 180 angles in a triangle add up to 180 sum of 2 angles in the triangle is the same value as the angle" outside the other angle of the triangle "
