    Which relationship is always correct for the angles x, y, and z of triangle ABC? A triangle ABC has angle ABC labeled as y, angle ACB labeled as z, and the exterior angle at A labeled as x. x + z = y y + z = x x + y + z = 180 degrees x + y + z = 90 degrees

    Recall, the sum of the three angles in a triangle is 180 degrees and the sum of the 2 angles that make up a straight line is also 180 degrees

    That missing angle at A is , 180 - y - z and the sum of that angle and x is 180, 180 = 180 - y - z + x

    So it is x+y+z=180 right?

    no, 180 = 180 - y - z + x 180 - 180 = x - y - z 0 = x - y - z x = y + z
