Answer:





Step-by-step explanation:
Part 1) Find the measure of angle 1
we know that
-----> by supplementary angles

Part 2) Find the measure of angle 2
we know that
-----> by alternate exterior angles
Part 3) Find the measure of angle 3
we know that
-----> by vertical angles
Part 4) Find the measure of angle 4
we know that
------> by corresponding angles
Part 5) Find the measure of angle 5
we know that
-----> by vertical angles
so

Part 6) Find the measure of angle 6
we know that
-----> by supplementary angles
we have

substitute


72/9 = 8
