Answer:
1. 35 = 5940°
sum = (n - 2) 180°
sum = (35 - 2) 180°
sum = (33) 180°
sum = 5940°
2. 14 = 2160°
sum = (n - 2) 180°
sum = (14 - 2) 180°
sum = (12) 180°
sum = 2160°
3. 14 = 2160°
sum = (n - 2) 180°
sum = (14 - 2) 180°
sum = (12) 180°
sum = 2160°
4. 56 = 9720°
sum = (n - 2) 180°
sum = (56 - 2) 180°
sum = (54) 180°
sum = 9720°
