Which relationship is always correct for the angles x, y, and z of triangle abc?
a. x + z= y
b. y + z = x
c. x + y + z = 180 degrees
d. x + y + z = 90 degrees

B. y + z = x

Step-by-step explanation:

Given: A triangle ABC in which is labelled as 'y' and is labelled as 'z' and x is an exterior angle to  .

We know that there is a property of triangles that the measure of exterior angle is equal to the the sum of the measure of the opposite interior angles.

Therefore, x=y+z

Thus, B. is the right answer.

i believe it is c.y = 9x
