Answer:

The measure of radius c is 12.36 cm

C is correct.

Step-by-step explanation:

Given: A regular pentagon is shown in diagram.

As we know the sum of angle of pentagon is 540°

It is a regular pentagon. Therefore, each angle is equal.

OB would be angle bisector of angle B

Thus,

In triangle OBC, ∠C=90°

Hence, The measure of radius c is 12.36 cm
