a regular polygon with an interior angle sum of 9000°? If so, what is it?
9000= (n-2)180 (n number of sides)
N= number of sides right?
using the formula sum of all the interior angles= (n-2)*180 degree where n = number of sides of the polygon hence 9000 = (n-2)180 divide both sides by 180 \[9000/180 = n-2\] \[50 = n-2\] transpose -2 to right hand side \[50+2=n\] \[52=n\] hence it is a 50-gon
Um.....
what does transpose mean?
of a matrix?
I dont know, it the answer the kushashwa gave, he says to "transpose the -2 to the right hand side"
It's just short for add 2 to both sides....
ok
I was looking over your method
9000/180 = number of lines???????
? 9000 = (n-2)180 = 180n-360 -> 180 n = 9360 -> n= 9360/180 = 52
maybe I don't understand the symbols and I am sorry if this is a silly question, but now did you go from 180n to 9360??
"transpose" the 360 from right side to left side (ie add 360 to both sides).
