Sum of interior angles = (p-2)*180 degrees
Sum of exterior angles = 360 degrees
You can go further than that only if the polygon is regular. In that case, all the interior angles are equal and each one is (p-2)*180/p degrees;
and all the exterior angles are equal and each is 360/p degrees.

What is the interior and exterior angles of a regular 8 sided polygon?
Interior angle: 135 degrees Exterior angle: 45 degrees
What is the name of the regular polygon interior is treble its exterior angle?
an octagon (8-sided)
What is the measure of the exterior angle of a 13 sided polygon if the interior angles vertex is 55 degrees?
If an interior angle is 55 deg, the corresponding exterior angle is 125 deg. This has nothing to do with the number of sides of the polygon (unless it is a regular polygon).
What is the measure of each angle in a 30 sided regular polygon?
Exterior angle: 12 degrees Interior angle: 168 degrees
What is the measure of each angle of a regular 15-sided polygon?
Exterior angle: 24 degrees Interior angle: 156 degrees
What is the exterior and interior angle of a regular 10 sided polygon?
Exterior = 36 degrees Interior = 144 degrees
What is the sum of the interior angles of a 102 sided-polygon?
Remember the two equations. Exterior angle = 360 / no. of sides. Interior angle = 180 - exterior angle. So for 102 sided polygon. exterior angle = 360/102 = 3.5294... Interior angle = 180 - 3.5294... = 176.4706.... Hence sum of the 102 sided polygon's angles is 102 X 176.4706 = 18,000 degrees. ( to nearest degree).

What is The interior Angle Of An 80 Sided Polygon?
Assuming it is an 80 sided REGULAR polygon, each exterior angle is 360/80 degrees = 4.5 degrees. So each interior angle = 180 - 4.5 = 175.5 degrees.
What is the size of an interior angle of a 20 sided regular polygon?
exterior angle = 360° ÷ 20 sides = 18° interior angle = 180° - exterior angle = 180° - 18° = 162°
What is the measure of each angle in a 30 sided regular polygon?
Exterior angle: 12 degrees Interior angle: 168 degrees
What is the measure of each angle of a regular 15-sided polygon?
Exterior angle: 24 degrees Interior angle: 156 degrees
What is the interior angle of a 12- sided shape?
The total interior angle of a 12 sided polygon is = (12 - 2) 180 degrees = 1800 degrees. The internal angle at each vertex of an regular dodecagon is equal to = = 150 degrees. While the exterior angle at a single vertex is = = 30 degrees. The total exterior angle of a 12 sided polygon is 360 degrees.
What is the name of the regular polygon whose interior angle is treble its exterior angle?
Interior angle = 3 x exterior angle. Hence Int Ang + Ext Ang = 180 Substituting 3 x Ext + Ext = 180 4 Ext = 180 Ext Angle = 180 / 4 = 45 degrees. And Exterior Ang;e = 360 / number of sides. number of sides = 360/ exterior angle No. of sides = 360/45 = 8 Hence the number of sides of the polygon is '8' . It is named as an OCTAGON.
What is the angle measure of a 50 sided polygon?
The interior angle of a regular polygon with x sides is 180(x-2)/x. As a result, each angle of a regular 50-sided polygon is 172.8. The exterior angles are 7.2
