If I read correctly, 2456 pennies needs to be divided simply by 3 then rounded to the nearest hundredth. So you would do 2456/3 3 goes into 24 how many times? Then 3 goes into 5 how many times, then continue the pattern. Once you've gotten a decimal to the thousandth, round the number to the hundredth and there you go

Step-by-step explanation:
=( n-2)180 
= ( 4 - 2 )180
= 360 
So, 144 + 90 + m<2 +m<1 = 360
 144 + 90 + 85 + m<1 = 360
 319 + m<1 = 360
 m<1 = 360 - 319
 m<1 = 41
their is an unknown angle so let's call it x 
let's find x first ( m<6=49)
x + m<6 = 180
x + 49 = 180
x = 180 - 49
x = 131
Now let's find m<7
m<7 + 38 + m<4 + x = 360
m<7 + 38 + 85 + 131 = 360
m<7 + 254 = 360
m<7 = 360 - 254
m< 7 = 106
