Best ResponseYou've already chosen the best response.1here you can apply the theorem of Carnot, namely: \[\Large \begin{gathered} {c^2} = {a^2} + {b^2}  2ab\cos \left( {22} \right) = \hfill \\ \hfill \\ = {16^2} + {10^2}  2 \times 16 \times 10\cos \left( {22} \right) = ... \hfill \\ \end{gathered} \]

Best ResponseYou've already chosen the best response.1ok! Now you have to compute this: \[\Large \sqrt {59.30} = ...?\]

Best ResponseYou've already chosen the best response.0none of it, i've been working on this for 3 days (not this particular question) and it only gets more and more confusing

Best ResponseYou've already chosen the best response.1we have: \[\large \begin{gathered} {c^2} = {a^2} + {b^2}  2ab\cos \left( {22} \right) = \hfill \\ \hfill \\ = {16^2} + {10^2}  2 \times 16 \times 10\cos \left( {22} \right) = \sqrt {59.30} \cong 7.7 \hfill \\ \end{gathered} \]

Best ResponseYou've already chosen the best response.0to see it written out, makes it somewhat easier but when its a different problem and i try and do it myself, i get it wrong
