*n*-gon. You know that all the interior angles are 144 degrees. What is the value of n?(n is the number of sides). Sofar I have 144n/n-2=180. I then simplified that to 144n=180n-360 by multiplying both sides by n-2 and distributing it on the right side. I can't seem to figure out where to go from here...
