Answer:

#45# sides

Explanation:

A regular polygon with #n# sides has a total of #(n-2)180^o# internal degrees. This can be understood as the number of triangles in which the polygon can be decomposed.
A regular polygon with an interior angle of #172^o# has a total of
#n 172^o#. So we have
#n 172 = (n-2)180#. Solving for #n# we have #n = 45#
