Answer:
z = 107, y = 25
Step-by-step explanation:
z and 73 are same- side interior angles and are supplementary, sum to 180°
z + 73 = 180 ( subtract 73 from both sides )
z = 107
z and (3y + 32) are vertical angles and are congruent, then
3y + 32 = 107 ( subtract 32 from both sides )
3y = 75 ( divide both sides by 3 )
y = 25
