Let AA and BB be acute angles such that sinA=810sinA=810 and cosB=817cosB=817. Enter the exact value of cos(A+B)cos(A+B) as a fraction in reduced form. cos(A+B)=cosA+B=

you should talk someone who owns the website about it. you did not deserve to have all that hard work and time taken away. id watch videos of little puppies to cool you down, and maybe some nacho cheese doritos.

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.
