Presumably the question concerns a hendecagon.
The sum of the interior angles of a n-gon are (n-2)*180 degrees.
For a hendecagon, the sum of the interior angles would be 9*180 = 1620 degrees.
If the hendecagon is regular, then all its interior angles are equal, and each is then 1620/11 = 147.2727.. degrees.

What is the size of one interior angle in a regular decagon?
Each interior angle measures 144 degrees
What is the size of each interior angle of a 12 sided polygon?
If it is a regular 12 sided polygon then each interior angle is 150 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 size of each exterior angle of a regular pentagon?
Interior angles are 108o. 360 - 108 = 252o for each exterior angle * * * * * Each exterior angle is 360/5 = 72 degrees, NOT 252. The 108 for the interior angle is correct, but to get from interior to exterior you subtract from 180, not 360!

Is it true that as the no. of sides of polygon increases each interior angle and exterior angle also increase?
No because each interior angle increases in size whereas each exterior angle decreases in size.
