Polygon angle sum theorems

30. 540

31. 720

32.360

33. 540

34. 180

35.900

Step-by-step explanation:

Sum of the angles = number of sides in the polygon -  two, all multiplied by 180 degrees.

*if you want to  find the measure of one interior angle, take that same formula and divide by the number of sides n: (n - 2) * 180 / n.

30 .

sum of the angles = (5-2)180

sum of the angles =540

31.

sum of the angles = (6-2)180

sum of the angles =720

32.

sum of the angles = (4-2)180

sum of the angles =360

33.

sum of the angles = (5-2)180

sum of the angles= 540

34. sum of the angles = (3-2)180

sum of the angles = 180

35.

sum of the angles = (7-2)180

sum of the angles = 900

step-by-step explanation:

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
