Answer:
A) 108 degrees
Explanation:
regular pentagon means all the inside angles of the pentagon are the same
to find the inside angles of any polygon you can use the formula:
180(n-2)/n=a
where n is number of sides
a is the measure of one of its interior angles
pentagon has 5 sides
= 180((5)-2)/5
=180(3)/5
=540/5
=108
each angle of the regular pentagon is 108 degrees
measure of angle C is 108
