Question

a regular polygon has 29 sides what is the size of each interior angle

Answer 1

there are several ways to do this...

1. find the size of 1 exterior angle = 360/29

then use the fact that the interior angle is supplementary


2. find the angle sum of the polygon using the formula

\[Sum = (n -2) \times 180\]

where n = the number of sides

then divide the angle sum by n to find 1 angle.

Hope it helps
