Answer:
[tex]n = \frac{S}{180} + 2[/tex]
Step-by-step explanation:
S = 180 × ( n - 2)
To solve for n divide both sides by 180°
That's
[tex]n - 2 = \frac{S}{180} [/tex]
Add 2 to both sides in order to isolate n
That's
[tex]n + 2 - 2 = \frac{S}{180} + 2[/tex]
We have the final answer as
[tex]n = \frac{S}{180} + 2[/tex]
Hope this helps you
