$\huge 180(n-2)$

2. jdoe0001

$$\bf \textit{sum of interior angles}=180(n-2)\qquad n=sides$$

3. jdoe0001

2- to get it for an octagon, well, 8 sides, n = 8 3- 6 sides, n = 6 4- 10 sides, n = 10

4. anonymous

So 180*6 for 2

5. jdoe0001

yeap 180 * (8-2) 180 * 6

6. anonymous

So 1080 is the answer
