The triangles shown below must be congruent.
A. True
B. False

Step-by-step explanation:

True. They are both 30-60-90 triangles, and the side opposite the 60° angle is 5 in both. The side opposite the 30° angle is 5/√3 and the side opposite the 90° angle is 10/√3.

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 %
