If the internal angles are 170 then the external are 180 -170 ie 10 deg. The sum of external angles is always 360 deg so there are 360/10 ie 36 sides. Alternatively, the internal angles of an n-sided polygon always sum to (180n -360) deg, so each angle = (180n -360)/n ie ((180n - 360)/n = 170 ie 180n - 360 = 170n ie 10n = 360 so n = 36

no a regular polygon has 360 degrees and it can have 4 or more sides
Smallest possible interior angle of regular polygon is 60 degrees (triangle). The greater the number of sides, the greater each interior angle. If exterior angle is 30 degrees, the polygon has 12 sides.
No regular polygon can have an interior angle of 180 degrees or more. No regular polygon can have an interior angle of 180 degrees or more. No regular polygon can have an interior angle of 180 degrees or more. No regular polygon can have an interior angle of 180 degrees or more.
The sum of the exterior angles of a regular polygon = 360° If an exterior angle measures 8° then the number of sides = 360/8 = 45
Providing that it is a regular polygon then it is a nonagon which has 9 sides
