Given the regular octagon, what is the length of any side?

110

Step-by-step explanation:x^2+17x=15x+35

x^2+17x-15x-35=0

x^2+2x-35=0

delta=2^2-4*1*(-35)=4+140=144

x1=(-2+V144)/2=(-2+12)/2=10/2

x=5

so 15*5+35=75+35=110

Step-by-step explanation:

In a regular polygon, each side has the same length.

Therefore we have the equation:

We must specify the domain:
