What is the value of z?

122 degrees, because x and z are alternate interior angles and are =

122 degrees, because 58 degrees and z are same side interiors which add to 180

32 degrees, because 58 and z are same side interiors which add to 90

the first and second answers are both correct

122 degrees, because x and z are alternate interior angles

122 degrees, because 58 degrees and z are same side interiors which add to 180

Step-by-step explanation:

1) we know that

m∠x=m∠z > by alternate interior angles

m∠x+58°=180° > by supplementary angles (form a linear pair)

m∠x=180°-58°=22°

therefore

m∠z=22°

2) m∠z+58°=180° > by same side interior angles

solve for z

m∠z=180°-58°=122°

therefore

122 degrees, because x and z are alternate interior angles

122 degrees, because 58 degrees and z are same side interiors which add to 180

it is b)

hope this : )
