Answer:
7.5 degrees
Explanation:
The rule for finding how many degrees total for all interior angles of a polygon is: (n−2) × 180° where n is the number of sides
The rule for finding how many degrees EACH angle is:
((n−2) × 180° )/ n where n is the number of sides
If a polygon has 16 sides:
((n−2) × 180° )/ n
= ((16-2) x 180)/16
= (14 x 180) / 16
= 157.5
If a polygon has 12 sides:
((n−2) × 180° )/ n
= ((12-2) x 180 )/ 12
= (10x180)/12
= 150
The difference:
157.5 - 150 = 7.5
