Answer:

Step-by-step explanation:
Just draw a rectangle, cut it into 3 horizontal lines, and cut it into 4 vertical lines.
<span>The sum of the interior angles of any regular polygon is (n - 2) X 180
30 = n
</span><span>[(30) - 2] × 180
</span>28 X 180
5040
<span>The interior angle of a regular polygon = the sum of interior angles ÷ number of sides</span>
5040 <span>÷ 30 = 168</span>
Therefore the measure of each interior angle in a regular 30-sided polygon is 168°
