I think it could be 13,17, and 15.
If I am wrong then I am sorry
12 because if u had 3 groups of 4 that would be 3+3+3+3
Answer:
Step-by-step explanation:
(t - 12) x 8 = 97
8t - 96 = 97
8t - 96 + 96 = 97 + 96
8t = 193
t = 24 1/2
Answer:

Step-by-step explanation:
We are asked to find the measure of each exterior angle of a regular dodecagon.
We know that a regular dodecagon is a 12 sided regular polygon with each side equal.
We know that measure of each angle of n-sided regular polygon can be found using formula:

Upon substituting
in above formula, we will get:


Therefore, the measure of each exterior angle of a regular dodecagon is 30 degrees.
