It I c because it just the answer
Step-by-step explanation:
the mistake was made when the value of cos 3 pi over 2 was calculated.
tan(A-B)= ?since tan=sin/cos
<u>sin</u><u>(</u><u>A-B</u><u>)</u> = <u>sinAcosB-cosAsinB</u>
cos(A-B) cosAcosB+sinAsinB
divide by cos on the RHS
tan(A-B)= <u>tanA-tanB</u>
1+tanAtanB
❄ Hi there,
let us combine the like terms and create an equivalent expression –
![\large\begin{gathered} \sf{9+a-5b-2} \\\sf{9-2+a-5b}\\\sf{7+a-5b} \end{gathered}](https://tex.z-dn.net/?f=%5Clarge%5Cbegin%7Bgathered%7D%20%5Csf%7B9%2Ba-5b-2%7D%20%5C%5C%5Csf%7B9-2%2Ba-5b%7D%5C%5C%5Csf%7B7%2Ba-5b%7D%20%5Cend%7Bgathered%7D)
That's as far as we can go.
