we have eleven sides in external and internalangle..
An undecagon, or figure with 11 sides. has an interior angle of 147o
Each internal angle measures 108 degrees
The number of sides of a regular polygon is 360 divided by the size of the exterior angle. The external angle is 180 - the internal angle. So for a regular polygon with an internal angle of 135 we get the following. 360 / (180 - 135) = 360 / 45 = 8 sides
That regular polygon would have 9 sides.

An undecagon, or figure with 11 sides. has an interior angle of 147o
Each internal angle measures 108 degrees
The smallest internal angle possible for a regular polygon is 60 degrees. So either the angle is not 12 degrees or it is not an internal angle.
An 11-sided polygon is called a hendecagon or undecagon. It has eleven straight sides and eleven angles. The shape can vary in appearance, depending on whether it is regular (with equal sides and angles) or irregular. In a regular hendecagon, each internal angle measures approximately 147.27 degrees.
To find the internal angle of a regular polygon with sides n, (n-2)/n * 180 3/5 * 180 = 108
The internal angles of a regular octagon can be calculated using the formula for the internal angle of a regular polygon, which is ((n-2) \times 180^\circ / n), where (n) is the number of sides. For an octagon ((n = 8)), the internal angle is ((8-2) \times 180^\circ / 8 = 135^\circ). Therefore, each internal angle of a regular octagon measures 135 degrees.
The number of sides of a regular polygon is 360 divided by the size of the exterior angle. The external angle is 180 - the internal angle. So for a regular polygon with an internal angle of 135 we get the following. 360 / (180 - 135) = 360 / 45 = 8 sides
Each interior angle of a regular decagon is 144 degrees
That regular polygon would have 9 sides.
