Find the measure of each interior angle of a regular polygon whose central angle measures

a) | 40°. | c) | 45°. |

To determine

**a) To find:**

The measure of each interior angle of a regular polygon.

Explanation

**Approach:**

1) The measure of any central angle of a regular polygon of *n* sides is given by

2) The measure of each interior angle of a regular polygon is given by

**Calculation:**

It is given that the central angle of the regular polygon is 40Â°.

Use the formula of central angle,

Substitute *c* = 40Â° in

To determine

**b) To find:**

The measure of each interior angle of a regular polygon.
