The sum of the interior angles of a polygon is (n-2)*180, n being the number of sides.
a nonagon has nine sides, so the total of interior angles is (9-2)*180=7*180
this is a regular nonagon, so each interior angle has the same degrees:
7*180/9=7*20=140
the exterior angle=180-the interior angle=180-140=40
40 is the correct answer.
Sixteen because if there are eight less tigers than lions at a zoo, then that means you add 8 to get the number of lions
3:15 because its till 3 o'clock and in each 1 theres 5 inside so 3x 5 = 15.
Thats how I got the answer 3:15 o'clock.
Hoped it help! :D
