Which relationship is always correct for the angles x, y, and z of triangle ABC? (1 point)

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

Answer 1

X + y + z = 180 degrees
