LESSON 17-1 PRACTICE In Items 14 and 15, the measures of two angles of a triangle are given.
Find the measure of the third angle of the triangle.
14. 23°, 78°
15. 105°, 40°

i used to know how to do this in 7th but i forget easily

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 %
