The equation for this is (n-2) x 180
Replace n with the number of sides:
a. 9: (9-2) x 180 = 7 x 180 = 1,260
b. 19: (19-2) x 180 = 17 x 180 = 3,060
The answer is 19 6×13 It’s 78-97 you get 19

Answer:
0.124
Step-by-step explanation:

To divide the numbers, we need to remove the decimal point
To remove decimal point , we multiply top and bottom by 100

Use long division. After using decimal point at the top we can include any number of zeros with 719
. 1 2 3 9
