which of the following is the measure of the sixth exterior anglea. 32b. 60c. 180d. 360

We have here a convex hexagon, and we have that the sum of the exterior angles of a polygon is always equal to 360 degrees. Then, we have:
[tex]80+68+84+56+40+x=360[/tex]Then, we have:
[tex]328+x=360\Rightarrow x=360-328\Rightarrow x=32[/tex]Therefore, the value for the sixth exterior angle is equal to 32 (option a).
