Answer 1

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

Answer 2

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

Answer 3

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

Answer 4

so first 180(16-2)

Answer 5

yes

Answer 6

what do you get

Answer 7

180(14)

Answer 8

keep going

Answer 9

2520

Answer 10

that's the sum of ALL the 16 angles

BUT...we just want one of them

Answer 11

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

Answer 12

157.5

Answer 13

good

Answer 14
