Question

S=(n-2).180
(Solve for n)

Answer 1

`n = (S)/(180) + 2`

Explanation:

S = 180 × ( n - 2)

To solve for n divide both sides by 180°

That's

`n - 2 = (S)/(180)`

Add 2 to both sides in order to isolate n

That's

`n + 2 - 2 = (S)/(180) + 2`

We have the final answer as

`n = (S)/(180) + 2`

Hope this helps you
