Solution for (n-2)*(180/n)=171 equation: 


D( n )

n = 0

n = 0

n = 0

n in (-oo:0) U (0:+oo)

(180/n)*(n-2) = 171 // - 171

(180/n)*(n-2)-171 = 0

180*n^-1*(n-2)-171 = 0

180*n^-1*(n-2)-171 = 0

9-360*n^-1 = 0

9-360*n^-1 = 0

-360*n^-1 = -9 // : -360

n^-1 = 1/40

-1 < 0

1/(n^1) = 1/40 // * n^1

1 = 1/40*n^1 // : 1/40

40 = n^1

n = 40

n = 40
