For #8, the formula for the sum of the interior angles of a polygon is S = 180(n-2) distribute to get S = 180n-180*2 S = 180n-360

I get that one now thank you can you help me with the others?

jimthompson5910 (jim_thompson5910):

for #9, use the formula in #8 and tell me what you get (when you plug in n = 16) Note: this is NOT the answer but it will get you there

OpenStudy (anonymous):

so first 180(16-2)

jimthompson5910 (jim_thompson5910):

yes

jimthompson5910 (jim_thompson5910):

what do you get

OpenStudy (anonymous):

180(14)

jimthompson5910 (jim_thompson5910):

keep going

OpenStudy (anonymous):

2520

jimthompson5910 (jim_thompson5910):

that's the sum of ALL the 16 angles BUT...we just want one of them

jimthompson5910 (jim_thompson5910):

so to just get the measure of just one of them, you divide by 16 (since every angle is congruent)

OpenStudy (anonymous):

157.5

jimthompson5910 (jim_thompson5910):

good

OpenStudy (anonymous):

thank you
