The formula for the sum of the degree measures of the interior angles of a polygon is s= 180(n-2). solve for n, the number of sides of the polygon, in terms of s

n = S/180 + 2

Step-by-step explanation:

S = 180(n - 2)

First, divide both sides by 180.

S/180 = n - 2

Now add 2 to both sides.

S/180 + 2 = n

n = S/180 + 2

n = (S/180) + 2

Step-by-step explanation:

You are solving for n, and so isolate the variable. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS:

First, divide 180 from both sides

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

S/180 = n - 2

Next, to isolate the variable (n) completely, add 2 to both sides

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

(S/180) + 2 = n

n = (S/180) + 2 is your answer
