Answer:
Option A
Step-by-step 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.
