Answer:
The Correct Option is Second one 108°.
Hence, the measure of each internal angle of a regular Pentagon is 108°.
Step-by-step explanation:
Given:
A Regular Pentagon.
Accordingly, for a Pentagon, the total of the internal angles is given by,
[tex]\textrm{Total Measure Internal Angles}=(5-2)\times 180\° = 3\times 180\°= 540\°[/tex]
In case of a regular Pentagon, all internal angles are equal.
Hence, divide the total above by 5.
[tex]\textrm{Measure of each angle of regular Pentagon}=\dfrac{540}{5}=108\°[/tex]
Hence, the measure of each internal angle of a regular Pentagon is 108°.
