Find the angle measure x in the given figure. |
|
Answer» 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] = 540° Since, it is a regular pentagon. It’s all interior angle will be equal. Size of Interior Angle x = 540/5 = 108° |
