Find the angle measure x in the given figure.
This is a regular pentagon, as all sides are of equal length.
AB = BC = CD = DE = EA
The sum of interior angles of poligon is
= (n – 2) × 180° [n is number of sides of polygon)]
= (5 – 2) X 180° [ for pentagon n=5]
Since, it is a regular pentagon. It’s all interior angle will be equal.
Size of Interior Angle x = 540/5
