I assume you mean the pentadecimal polygon is regular: 156o.
For any polygon the exterior and interior angles are supplementary, that is:
interior_angle + exterior_angle = 180o
For a regular polygon:
Exterior_angle = 360o ÷ number_of_sides
Interior_angle = 180o - exterior_angle
= 180o - (360o ÷ number_of_sides)
For a pentadecimal polygon with 15 sides:
interior_angle = 180o - (360o ÷ 15)
= 156o

What is the Definition an interior angle of a polygon?
A polygon is a closed plane figure bounded by straight sides. Since it is a closed surface, it has an interior (inside) and an exterior (outside). The interior angle of a polygon is the angle formed by two adjacent sides such that the angle is facing the interior of the polygon.
What type of an interior angle of a polygon and its adjacent exterior angle are complementary?
The interior angle of a polygon and its adjacent exterior angle can never be complementary.
What is the interior angle of a twenty-four-sided polygon?
If the polygon is regular, the measure of one interior angle of a 24 side polygon is 165 degrees.
The supplement of an exterior angle of a polygon is the?
interior angle
An interior angle of a polygon that is not adjacent to the exterior angle?
Ah...
How many sides does a regular polygon if its interior angles are 270?
No regular polygon can have an interior angle of 180 degrees or more. No regular polygon can have an interior angle of 180 degrees or more. No regular polygon can have an interior angle of 180 degrees or more. No regular polygon can have an interior angle of 180 degrees or more.

What is the interior angle of a regular 24 sided polygon?
interior angle of an n-sided polygon = (180(n-2)/n)°interior angle of a 24-sided polygon = (180x22/24)° = 165°
What polygon has an interior angle of 144 degrees?
Any polygon can have an interior angle of 144 degrees. The measurement of an interior angle of a decagon is 144 degrees.
If the exterior angle of a regular polygon is 20 what is the interior angle of this polygon?
160
What is the interior angle of a twenty-four-sided polygon?
If the polygon is regular, the measure of one interior angle of a 24 side polygon is 165 degrees.
What is each interior angle of a 12 sided polygon?
Each interior angle in 12-sided polygon is 150 degrees.
What is the Interior angle of a polygon with 15 sides?
The interior angles of a 15 sided polygon add up to 2340 degrees and if it is a regular polygon then each interior angle is 156 degrees.
The supplement of an exterior angle of a polygon is the?
interior angle
What is the interior angle?
The angle inside a polygon. Simple!
How do you find a number of sides of a polygon with the measure of its interior angle?
If its a regular polygon then 180-interior angle and divide the answer into 360 which will give the number of sides of the polygon.
