Find sin (A-B) if sin A = 4/5 with A between 90 and 180 and if cos B = 3/5 with B between 0 and 90
quester [9]

Answer:

sin(A-B) = 24/25

Step-by-step explanation:

The trig identity for the differnce of angles tells you ...

sin(A -B) = sin(A)cos(B) -sin(B)cos(A)

We are given that sin(A) = 4/5 in quadrant II, so cos(A) = -√(1-(4/5)^2) = -3/5.

And we are given that cos(B) = 3/5 in quadrant I, so sin(B) = 4/5.

Then ...

sin(A-B) = (4/5)(3/5) -(4/5)(-3/5) = 12/25 + 12/25 = 24/25

The desired sine is 24/25.

In a recent? year, person A and person B had two concert? tours, and together they generated $ 192.9 million in ticket sales. If
Nuetrik [128]

Answer: Person A generates 107.6 millions and person B generates 85.3 millions.

Step-by-step explanation:

Let 'x' millions be the amount generated by person A then the amount generated by person B be 'x-22.3' millions.

Since they both earn together $192.9 millions.

So according to the our assumptions we have,

x+x-22.3=192.9\\\Rightarrow\ 2x=192.9+22.3\\\Rightarrow\ 2x=215.2\\\Rightarrow\ x=107.6

Therefore, the amount generated by person A=107.6 millions

And the amount generated by person B= 192.9 millions - 107.6 millions

=85.3 millions
