Answer: The measure of each interior angle of a regular octagon can be found using the formula:
(n-2) x 180 / n
Where n is the number of sides in the polygon.
For Octagon, n=8
So we can substitute 8 for n in the formula:
(8-2) x 180 / 8 = 6 x 180 / 8
Therefore, each interior angle of the base of Octagon Towers measures 135 degrees.
