Answer: to realyy get in these sentences, you have to use big words, the explain to them what it means, so you use extra words to elaoborate on what it means.
Explanation:
Serbian is the only adjective.
Recall the compound angle formulae:
sin(A+B) = sinAcosB + cosAsinB
cos(A+B) = cosAcosB - sinAsinB
sin(A+B) + cos(A+B) = sinAcosB + cosAsinB + cosAcosB - sinAsinB
I think?? It looks a little too complicated to be the answer though
(Btw this is Math haha why is this question under English)
