Answer:
The sum of the interior angles of a 10-sided polygon is 1,440 degrees.
To find the sum of the interior angles of any polygon, you can use the formula:
sum of interior angles = (n - 2) x 180 degrees
where n is the number of sides of the polygon.
So, for a 10-sided polygon, we have:
sum of interior angles = (10 - 2) x 180 degrees
sum of interior angles = 8 x 180 degrees
sum of interior angles = 1,440 degrees
Therefore, the sum of the interior angles of the 10-sided polygon on the left is 1,440 degrees.
