How many sides has an equiangular polygon if one of its exterior angles is 25 5/7?
lys-0071 [83]
Step One
Figure out the interior angle
25 5/7 = 25.714285 repeating. The interior angle is the supplement of this angle.

180 - 25.714285 = 154.2857
The formula relating the number of sides and the interior equal angle is

interior equal angle = 180 ( 1 - 2/n) where n is the number of sides. (Google equiangular polygon to find this formula.)

154.2857 / 180 = 1 - 2/n) 
0.8571428 = 6/7 = 1 - 2/n
1/7 = 2/n
n = 14 sides
This figure is regular as well as equiangular.

Explain how your model for 3/5 minus 1/2 is different from your model for 3/5 minus 3/10
TEA [102]
It is different because to find out the answer, change all denominators to 10, since the LCD is 10. 6/10-5/10=1/10 6/10-6/10=0/10 1/10 is not equal to 0/10
