Answer 1

Formula Used:

Measurement of each angle of the pentagon = \(\frac{(n - 2) \times 180}{n}\)

Calculation:

Pentagon has five sides so, n = 5

⇒ Measurement of each angle of the pentagon = \(\frac{(5 - 2) \times 180}{5}\)

∴ Measurement of each angle of the pentagon = 108°

The correct option is 2 i.e. 108°
