Given that the polygon has 14 sides.
So, sum of external angles = 360 deg. (As the external angle of any polygon is always 360 deg.)
Now, Sum of internal angles. ....
Using the Formula...
Sum of internal angles = (n - 2) × 180, where n = no. of sides.
Therefore, (14 - 2) × 180
= 12 × 180
= 2160 deg.
