Which sum or difference identity could be used to prove that sin(pie + q) = -sin q

see below

Step-by-step explanation:

sin(a+b) = sin(a)cos(b) + cos(a)sin(b)

sin(π+q) = sin(π)cos(q) + cos(π)sin(q)

sin(π) = 0

cos(π) = -1

therefore

sin(π+q) = 0*cos(q) -sin(q) = -sin(q)

found it xd it ok yt

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
