The formula would be 2x-5=x+1. After PEMDAS it would be x=6
A regular dodecagon is a polygon with 12 equal sides.
Length of each side = 108/12 = 9 cm.
Length of the apothem = (9/2)/tan 15 = 9/2tan 15 = 16.79 cm
Area of each triangle = 9/2(16.79) = 75.57 cm^2
Therefore, area of the dodecagon = 12(75.57) = 906.9 cm^2
The answer there is 1000000
1. n= 2.67
2. x= 5
3. x= 50
4. r= 13
if you get number four wrong i'm sorry ....
