we know that

If lines p and q are parallel

then

[tex]x=z[/tex]---------> by corresponding angles

[tex]x+y=180\°[/tex] -------> by consecutive interior angles

Let's verify all the equations to determine the solution to the problem.

Equations

case A) [tex]x=z[/tex]

The equation guarantees that the lines p and q are parallel (see the procedure)

case B) [tex]x+y=180\°[/tex]

The equation guarantees that the lines p and q are parallel (see the procedure)

case C) [tex]x+z=180\°[/tex]

The equation does not guarantee that the lines p and q are parallel. The only way would be that x-angle and z-angle are right angles

case D)  [tex]x=y[/tex]

The equation does not guarantee that the lines p and q are parallel. The only way would be that x-angle and y-angle are right angles

case E)  [tex]y+z=180\°[/tex]

The equation is always true, but toes not guarantee that the lines p and q are parallel.

therefore

the answer is

[tex]x=z[/tex]

[tex]x+y=180\°[/tex]

Answer:  The correct options are

(A) x = z.

(B) x + y = 180°.

Step-by-step explanation:  Given that the letters x, y and z are angle measures.

We are to select the correct equations that would guarantee that lines p and q are parallel.

Since the lines p and q are parallel, so

(i) the angles with measures x and y are interior angles on the same side of the transversal

and

(ii) the angles with measure x and z are corresponding angles.

We know that

if two parallel lines are cut by a transversal, then the measures of the corresponding angles are equal

and

the sum of the measures of the interior angles on the same side of the transversal is 180°.

Therefore,

x + y =180°, since they are interior angles on the same side of the transversal

and

x = z, since they are corresponding angles.

Thus, the correct options are

(A) x = z.

(B) x + y = 180°.
