Beyond the Answer
To solve the problem, we start by letting the exterior angle be
. According to the information given, the interior angle is
. The relationship between the interior and exterior angles of a polygon is given by:
Substituting the values we have:
This simplifies to:
Dividing by 20:
Now, to find the interior angle:
Next, we can find the number of sides
of the polygon using the formula for the exterior angle:
Setting this equal to
:
Rearranging gives:
Thus, the interior angle is
and the polygon has
sides.
