11. To estimate the height of his school, a student positions himself so that his line of sight to the top of the school and his line of sight to the bottom form a right angle. What is the height of the school?

the amount you'd have after the work is $1.55

step-by-step explanation:

you subtract 95% from $31.

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 %  

step-by-step explanation:

is there more to this question?

the answer to this is a. a^2 + b^2 = c^2
