    The total degrees in a triangle is 180. if you add the angles up, it should equal. if we say that the angle of the third angle is y, our equation looks like this

    y+x+86=180

    if we solve for y, we get

    y=180-86-x, which you can solve for for your answer

    The correct answer would be A, 86-x

    the sum of a triangle will always be 180 the grease.
