Answer:

Option A

Explanation:

We are given that a regular pentagon

We know that a regular pentagon is that type of figure in which is five equal sides and five equal angles.

The measure of an interior angle of a regular pentagon=
$108^(\circ)$

The sum of the interior angle measures of a regular pentagon=
$540^(\circ)$

We know that sum of interior angles measures of convex or concave polygon =
$180(n-2)^(\circ)$

n=5 then

The sum of interior angle measures of a convex pentagon =
$540^(\circ)$

The sum of interior angle measures of a concave pentagon=
$540^(\circ)$

Hence, the angle of measure of a interior angle of a regular pentagon is different from others.
