To find the sum of the measures of all angles in any 10-gon, we need to know the formula for calculating the sum of angles in a polygon.
The formula for finding the sum of the measures of all angles in a polygon is:
Sum of angles = (n - 2) * 180 degrees
Where 'n' represents the number of sides of the polygon.
For a 10-gon, we have 'n' = 10. Plugging this into the formula, we get:
Sum of angles = (10 - 2) * 180 degrees
= 8 * 180 degrees
= 1440 degrees
Therefore, the sum of the measures of all angles in a 10-gon is 1440 degrees.
