Find the measure of a central angle of a regular polygon of a) 8 sides. c) 9 sides. b) 10 sides. d) 12 sides.

To determine

a) To find:

The measure of a central angle of a regular polygon of 8 sides.

Explanation

Approach:

The measure of any central angle of a regular polygon of n sides is given by c=360n

Calculation:

It is given that number of sides of the regular polygon is 8.

Use the formula of central angle, c=360n

Substitute n = 8 in c=</

To determine

b) To find:

The measure of a central angle of a regular polygon of 10 sides.

To determine

c) To find:

The measure of a central angle of a regular polygon of 9 sides.

To determine

d) To find:

The measure of a central angle of a regular polygon of 12 sides.
