How many sides does a regular polygon have if each of its interior angles is $ 165^{\circ} $?

We know that,

For a regular n-sided polygon:

Each interior angle = 180−($\frac{360\degree }{n}$)

Given that,

Each interior angle measures 165°.

Let the number of sides be n.

Therefore,

$\begin{array}{l}$
165\degree =180\degree -\left(\frac{360\degree }{n}\right)\\
\\
\frac{360\degree }{n} =180\degree -165\degree \\
\\
\frac{360\degree }{n} =15\degree \\
\\
n=\frac{360\degree }{15\degree }\\
\\
n=24
\end{array}

The number of sides is 24.
