Answer:
Step-by-step explanation:
Notice that you don't need to evaluate the actual sin and cos functions, since you are in the presence of a well known Pythagorean identity that states that this type of addition of squares for the same angle should equal 1:
So, as long as the angle "x" is the same in both trig functions, this addition should render "1" (one).
Because in this case the angle involved is the same (in both cases pi/4), the identity is valid.
Cost of chicken wings at Buffalo Bills = 8 wings for $7
Cost of 1 wing at Buffalo Bills =
Cost of chicken wings at Buffalo Mild Wings = 12 wings for $10
Cost of 1 wing at Buffalo Mild Wings =
Cost of chicken wings at Wingers = 20 wings at $17
Cost of 1 wing at Wingers =
Hence, comparing all the three costs per wing, we can see that Buffalo Mild Wings is serving chicken wings at lowest price of $0.833 per wing.
