Question

HURRY!!!What is the sum of the measures of the interior angles of a 12-gon?
1. 1620
2. 1800
3. 1980
4. 2160

Answer 1

If we have n angle the formula for the sum of internal angles is:
sum = 180*(n-2)

in this case n=10,
so the answer will be 180 * 10 = 1800

Answer 2

The answer would be 2). 1,800 degrees..
