107, y = 25Step-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 = 107z and (3y + 32) are vertical angles and are congruent, then3y + 32 = 107 ( subtract 32 from both sides )3y = 75 ( divide both sides by 3 )y = 25
