s=%28n-2%29%2A180

Solve for n:

Write the 180 on the left of the parentheses:

s=180%28n-2%29

Distribute:

s=180n-360

Add 360 to both sides:

s%2B360=180n

Divide both sides by 180

%28s%2B360%29%2F180=n

or turning it around:

n=%28s%2B360%29%2F180

angle=[180(n-2)]/n.

Typically, your angle will be given. Cross multiplying, you can solve for n.
