Question

4. Find the measure of each interior angle of a regular polygon with 12 sides.

1800 degrees
150 degrees
180 degrees
145 degrees

Answer 1

For any regular polygon the formula for each interior angle is (180(n-2))/n where n is the number of sides.
Now we'll put 12 in there and it is:
(180(12-2))/12
180(10)/12
1800/12
150 degrees.

Hope this helps :)
