Question

Solve for n.........

Answer 1

`n=(-360)/(A-180)`

Explanation:

Step 1: Write out equation

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

Step 2: Multiply both sides by n

`An=180(n-2)`

Step 3: Distribute

`An=180n-360`

Step 4: Subtract 180n on both sides

`An-180n=-360`

Step 5: Factor out n

`n(A-180)=-360`

Step 6: Divide both sides by (A - 180)

`n=(-360)/(A-180)`
