Best ResponseYou've already chosen the best response.1soooo 1000cosC+169=1025 1000cosC=846 cosC=846/1000 C=arccos(846/1000), right?

Best ResponseYou've already chosen the best response.2\(\color{blue}{\text{Originally Posted by}}\) @BloomLocke367 soooo 1000cosC+169=1025 1000cosC=846 cosC=846/1000 C=arccos(846/1000), right? \(\color{blue}{\text{End of Quote}}\) 1025169 = 856 not 846
