360 degrees and the polygon is an equilateral triangle.
If exterior angles are 120 then interior angles must be 60 so you have an equilateral triangle
The sum of a regular polygons exterior angles always = 360

The exterior angles of any polygon add up to 360 degrees.
360 degees
The sum of the measures of the exterior angles of any polygon, regular or irregular, is always 360 degrees. In a regular polygon with ten sides, each exterior angle measures 360 degrees divided by the number of sides, which in this case is 36 degrees. Therefore, the sum of the measures of the exterior angles of a regular decagon is 10 multiplied by 36 degrees, which equals 360 degrees.

Hint: in a regular polygon interior plus exterior = 180o, always.
The exterior angles of any polygon add up to 360.
How many sides does a regular polygon have if each exterior angle measures 20?
The exterior angles add up to 360 degrees
If exterior angles are 120 then interior angles must be 60 so you have an equilateral triangle
The sum of a regular polygons exterior angles always = 360
360
The exterior angles of any polygon add up to 360 degrees.
The exterior angles of any polygon add up to 360.
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
