The sum of the external angles of every polygon = 360 degrees
So the n-gon must have its interior angle sum = 360 degrees also.
So what polygon has interior angle sum = 360?
62 inchezzzzzzz so 60-4 = 56 --- 56 +6 = 62
Answer : Original price $5
Equation 80%/100% $4/?
1) Multiply 100 by 4 which gives you 400
2) divide 400 by 80 which gives you 5
Turn 5 into $5
We have that
2.45----------------- > 100%
2.80------------------X
x=2.80*100/2.45=114.29
114.29-100=14.29%-- >14%
the answer is 14%
