Answer:

y = 111 , z = 32

Explanation:

3z - 27 and 69 are alternate exterior angles and are congruent (equal), so

3z - 27 = 69 ( add 27 to both sides )

3z = 96 ( divide both sides by 3 )

z = 32

------------

3z - 27 and y are a linear pair and sum to 180 , that is

3z - 27 + y = 180 ( from above , 3z - 27 = 69 )

69 + y = 180 ( subtract 69 from both sides )

y = 111
