Answer 1

Answer:

• 9 sides

Step-by-step explanation:

Each central angle represents a side of the polygon.

The number of sides is:

• 360 / 40 = 9

Answer 2

• Created angle=40°

We know in a circle the centre angle is 360°

• Now each side is corresponded by the centre.

So number of sides of polygon

$\\ \sf\longmapsto \dfrac{360}{40}$

$\\ \sf\longmapsto \dfrac{36}{4}$

$\\ \sf\longmapsto 9$
