Answer:
n = s/180 +2
Explanation:
180 (n-2) = s
Step 1: To find n, we need to get rid of 180 from the left side of the equation. Divide 180 by both sides; then we can cross out 180 with itself on the left, leaving (n-2)
180 (n-2) /180 = s/180
Step 2: Now we got rid of 180 on the left, we must isolate n. To do that, we must bring -2 to the other side of the equation. There, it would become positive, and n gets isolated.
n = s/180 + 2
Although, you may or may not be confused with my answer, and I realized that there's two ways to solve this. Let me show you:
Step 1: 180(n-2) = s
Distribute - multiply 180 with every term in the brackets, which then we would end up with:
180n-360 = s
Step 3: Bring -360 to the right side of the equation, where it would become positive.
180n = s+360
Step 4: To isolate n, divide 180 by both sides of the equation:
180n/180 = s+360/180
Step 4: Now you have:
n = s+360/180.
Though you could leave your answer as the one above, you should simplify it.
Step 5: n = s/180 + 360/180
360/180 = 2, therefore the simplified answer is:
n = s/180 +2
