If a regular polygon has an exterior angle of 7.2°, then determine the sum of all the interior angles.

8640

Step-by-step explanation:

All exterior angles must = 360 degrees.

360/7.2= 50

There are 50 exterior angles, so it's logically concluded that there are 50 sides.

Interior angle= 180-7.2= 172.8

172.8 x 50= 8640.

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%
