A thanksgiving day promotion included $1 mail-in rebate for the purchase of a turkey wing at least 20 lb. Esther Robert purchased a 22-pound turkey for $1 and seventy-nine a pound. What did it cost for after rebate if an envelope cost $0.15 and a stamp cost $0.39?

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
