Answer
Each interior angle of a regular octagon is (135)°.
Solution:
Octgon has 8 sides.
$\therefore$ Interior angle $=\frac{180^\circ\text{n}-360^\circ}{\text{n}}$
Interior angle $=\frac{(180^\circ\times8)-360^\circ}{{8}}=135^\circ$
Solution:
Octgon has 8 sides.
$\therefore$ Interior angle $=\frac{180^\circ\text{n}-360^\circ}{\text{n}}$
Interior angle $=\frac{(180^\circ\times8)-360^\circ}{{8}}=135^\circ$
