What is the measure of the missing angle?

60 degrees

Step-by-step explanation:

Every Triangle has an angle of 180 degrees

so if we add all of the written angles which is 25 + 35 + 60 = 120

we take 180 degrees and subtract it with the previous answer (120)

180 - 120 = 60

Therefore it is 60 degrees

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 %
