n is number of sides. Sum of interior angles is 180n - 360, so 180n = 2880 + 360, ie 3240 and n = 3240/180 ie 18.
Each interior angle of a regular pentagon is 108 degrees ie all five of them are larger than a right angle. If the pentagon is convex, at least four of the angles must be greater than 90 degrees.
It is because if you shorten the sides yet keep the angles the same size, the shape will eventually become a pinwheel and thus, because a circle is always 360 degrees, the outer angles will always be 360 degrees.
The easiest way to calculate this is to use the facts thatthe sum of the interior and exterior angles is 180o; andthe sum of the exterior angles of any polygon is 360o.For a regular polygon, each exterior angle will be 360o divided by the number of sides. The interior angle is then 180o - the exterior angle.For a 31-gon:exterior_angle = 360° ÷ 31= 1119/31o⇒ interior_angle = 180° - 1119/31o= 16812/31°≈ 168.39oUse the Interior Angle Formula directlyThe sum of interior angles for a polygon of n sides is (n-2) x 180° and individual angles for a regular polygon will be (n-2) 180°/nPlugging in the value n=31, we have one angle = 29(180)/31 = 168.39°

The sum of the interior angles of a n-gon is (n-2)*180 degrees. n = 7, so sum of interior angles = (7-2)*180 = 5*180 = 900 degrees.
It depends on convex WHAT!
