Each interior angle of a regular polygon is 108^\circ. How many sides has it?
A
5
B
7
C
9
D
14
Verified Correct Answer: A.
Step-by-Step Mathematical Solution
The exterior angle of the polygon = 180 – 108 = 72^\circ. The sum of exterior angle of the regular polygon = 360^\circ
The number of sides \(=\frac{360}{72}=5\)
