Answer:
How to do 29-32 = ((n-2) x 180°)/n -- Which means subtract 2 from the number of sides and multiply by 180. This is how many degrees are in the shape overall so then you take that number and divide it by the # of sides to know how many degrees each angle is.
29) ((12-2) x 180)/12 = 150°
30) ((11-2) x 180)/11 = 147.27°
31) ((21-2) x 180)/21 = 162.86°
32) ((15-2) x 180)/15 = 156°
How to do 33-36 = Just plug it into the equation from before and solve for n ((n-2) x 180°)/n = ?
33) ((n-2) x 180°)/n = 60
Answer = 3
34) ((n-2) x 180°)/n = 20
Answer = 2.25 (I checked this multiple times I think the question is wrong)
35) ((n-2) x 180°)/n = 72
Answer = 3.33 (I have no idea why theyre having the answers as decimals)
36) ((n-2) x 180°)/n = 10
Answer = 2.12 (I did it right so this is quite weird)
