How did you've get 154.3
The sum of the interior angles of a 14-gon = (14-2)*180 = 2160 degrees. divide it by 14 so you get something 154.3

The polygon has 14 sides.
---------------------------------------------------------------------------------------------------
STEP 1: Find Sum of all interior angles:
The formula to find sum of all interior angles is (n - 2) x 180, where n is the number of sides.
So for this 14-gon,
Sum of interior angle = (14 - 2) x 180 = 2160°
---------------------------------------------------------------------------------------------------
STEP 2: Find 1 interior angle:
There are 14 sides, therefore there are 14 angles.
To find 1 angle, we divide the total sum of all angles by 14:
1 angle = 2160 ÷ 14 = 154.3°
---------------------------------------------------------------------------------------------------
Answer: one interior angle is 154.3°
