The sum of the interior angles of a polygon with n sides is (n-2)*180 degrees. So, with n = 13, the sum of the interior angles is 11*180 = 1980 degrees.
However, any particular interior angle can have any value between 0 and 360 degrees, (not inclusive of those limits). It is only in the case of a REGULAR polygon that the value of the interior angle can be determined without additional information.
So, if the 13-polygon is regular, then each interior angles is 1980/13 = 1524/13 or 152.3077 degrees.

What is an exterior angle of a triangle?
It is: 180-interior angle = exterior angle
What do you call an angle inside a shape?
Interior angle
What is the interior angle and exterior angle measure with 13 sides?
Assuming you mean for a regular triskaidecagon (a polygon with 13 sides): Each exterior angle is 360o ÷ 13 = 279/13o ≈ 27.69o Each interior angle is 180o - 279/13o = 1524/13o ≈ 152.31o
What is the measure of a polygons interior angle?
It is: 180-exterior angle = interior angle
What is the intereor angle of a triangle?
An interior angle is any angle on the interior of the triangle.
Which of these is the alternate interior angle of angle hge?
GEF is the alternate interior angle of angle hge.
What is an exterior angle of a triangle and how does the measure of an exterior angle relate to the interior angles?
Exterior angle+interior angle=180 degrees and 180-exterior angle=interior angle
A 13 sided polygon equals how many degrees for its interior angles?
A 13 sided polygon also called a triskaidecagon or tridecaogn has a total 1980 degrees for its interior angles.
What is the exterior and interior angle of a heptagon?
the interior angle is about 128.571428 the exterior angle is about 51.4285
What is allied angle?
An allied angle is an angle that is found on an interior line. An interior angle is the angle where to lines come together.
Interior angle of and 18 sided shape?
Exterior angle + interior angle = 180 Hence Interior Angle = 180 - Exterior Angle The Exterior Angle = n(No. of sides ) / 360 Substituting Interior Angle = 180 - (n/360) Interior Angle = 180 - (18/360) Interior Angle = 180 - (1/20) Interior Angle = 179.95 degrees.
Is the vertex of the angle in the interior of the angle?
No. It forms the angle and so is neither in the interior nor the exterior.
How do you measure the interior angle of a polygon?
With a protractor or if you know the exterior angle then it's 180 - exterior angle = interior angle
What is the sum of an interior angle on a quadrilatral?
An interior angle is the inside angle of a shape e.g quadrilateral, square
