What is measure of angle a?
enter your answer as a decimal in the box. round only your final answer to the nearest hundredth.

A = 53.13 degrees

Step-by-step explanation:

sin theta = opposite side/ hypotenuse

sin A = 4/5

Take the inverse of each side

sin ^-1 sin A = sin ^-1 (4/5)

A = 53.13010

To the nearest hundredth

A = 53.13 degrees

if x decreases by 4 then y increases by 10

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 %
