Question

The sum of the measures of the interior angles of a 47-gon is ___ degrees.

Answer 1

172.3 to 1 decimal place

Explanation:

So first you do 360÷47=7.659574468… we then round it to 4 decimal places which is 7.6596. Then you do 180-7.6596=172.3404. So the answer is 172.3404 but to 1 decimal place it is 172.3.
