Question

in a regular polygon, the measure of each interior angle is 108° . How many sides does the polygon have? the polygon has _____ sides

Answer 1

In order to determine the number of sides of the polygon, take into account that each exterior angle is equal to:

180° - 108° = 72°

the number of sides is given by the quotient in between 360° over the value of the exterioir angle:

360°/72° = 5

Hence, the given polygon has 5 sides
