Review what you know about the angles of polygons below. 

1. If the exterior angle of a polygon is $29^\circ$, what is the interior angle?

   Answer (a):

   $180^\circ - 29^\circ = 151^\circ$

2. If the interior angle of a polygon is $170^\circ$, can it be a regular polygon? Why or why not?

   Answer (b):

   Yes, a regular $36$-gon has interior angles of $170^\circ$.

3. Determine the sum of the interior angles of a regular $29$-gon.

   Hint (c):

   $(n - 2)(180^\circ) =$ sum of the interior angles
