Answer:

D. 120 degrees.

Explanation:

We nee to find the measure of the interior angle in a regular hexagon.

The exterior angle = 360 / 6 = 60 degrees. ( In all convex polygons the sum of the exterior angles = 360 degrees).

So α = 180 - 60 = 120 degrees (adjacent angles add up to 180 degrees).

Answer:

formula for sum of interior angles is (n-2)*180 - for a regular polygon

divide that by the number of sides

so 6-2 = 4*180 =720 degrees

720/6 = one angle(angle a) =120
