Answer:

n = 5

Step-by-step explanation:

180(n − 2) = s

180(n − 2) = 540

180n - 360 = 540

180n - 360 + 360 = 540 + 360

180n = 900

(1/180) 180n = 900 (1/180)

n = 5
N = 5 , so first we divide by 180 on both sides
Since you do the opposite of multiplication making N-2=3 , the. add 2 on both sides since that’s the opposite of subtracting N=5
