A 29 sided polygon is called icosikainonagon ( I think )
29
I believe a scalene triangle CAN have a right angle. Def of scalene tri: a triangle with no equal sides, and no equal angles. A triangle with angles of 90, 29, and 61. Sides of 15.0, 27.0, and 30.9 this satisfies the definition. If you look at it the other way: can a right triangle be non-scalene, and there is only one possibility: the isosceles right triangle (45°, 45°, 90°), with sides (square_root(2), 1, and 1). It's not possible for an equilateral triangle to have a right angle. So all other right triangles are scalene (but not all scalene triangles are right triangles).
I suggest you forget about memorizing fancy names - which really serve no useful purpose - and just call them "20-sided polygon", "21-sided polygon", etc.
Since the angle of 331⁰ is in the fourth quadrant, then the measure of its reference angle in the first quadrant is 360⁰ - 331⁰ = 29⁰ .
A 29-sided polygon.
It could be any size at all, just as long as all 29 of them add up to 4,860 degrees.If the polygon is regular, then each interior angle is 16717/29 degrees.
An interior angle of a 30-sided polygon can have any value between 0 and 360 degrees : with the possible exception of 180 degrees - which would make it a 29 sided polygon!
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 formula for the sum of the interior angles of a shape with n sides is: 180 * (n - 2) So, for a 31 sided shape, the sum of the interior angles is 180 * 29 = 5,220.
It is a 29 sided polygon whose interior angles add up to 4860 degrees
The formula for the number of diagonals that an N-sided polygon has is# diagonals = N(N-3)/2N(N-3)/29(N-3)/29*(9-3)/29*6/2 = 54/227
All interior angles of any triangle amount to 180 degrees. 180-90-29 = 61 So the third angle will be 61 degrees.
Sum of exterior angles = 360 deg Sum of interior angles = (29-2)*180 = 4860 degrees.

No because the interior angles of a triangle must add up to 180 degrees.
The name of a 29 sided polygon is Icosikaienneagon.
