Answer 9

If you'd please look up "interior angles of a polygon," you'll likely find a formula for the sum of the interior angles of a polygon of n sides. Please try that. Come back here if you still feel stuck.

Hint: "octa-" means 8 of something. Thus, the value of 'n' in the formula mentioned above will be 8: n=8.
