It says to find the sum of the angle measures in a 16-gon.
We have a formula to find the sum of interior angles of polygon with 'n' sides.
Sum = (n-2)·180°
Here the value of n would be 16 for a 16-gon.
So, sum = (16-2) × 180° = 14 × 180° = 2520°
Hence, the sum of the angle measures in a 16-gon is 2520°
