Answer: 1800
Step-by-step explanation: The total interior angle of a 12 sided polygon is = (12 - 2) 180 degrees = 1800 degrees.
For this case we have that by definition, the sum of the internal angles of a polygon of n sides is given by:
[tex](n-2) * 180[/tex]
Where:
n: Represents the number of sides
According to the data, we have a 12-sided polygon, so [tex]n = 12:[/tex]
[tex](12-2) * 180 = 10 * 180 = 1800[/tex]
Thus, the sum of the internal angles is 1800 degrees.
Answer:
1800 degrees
