$*5-72.$ please help! thank you

The pole is subjected to the two forces shown. Determine

the components of reaction of A assuming it to be a ball$-$

and$-$socket joint. Also, compute the tension in each of the

guy wires, $BC$ and $ED.$

Ans: widehat$(ED)=($:$-\frac{2}{3},-\frac{1}{3},-\frac{2}{3}$:$),$widehat$(BC)=($:$\frac{12}{17},-\frac{9}{17},-\frac{8}{17}$:$)F_{BC}=$

$205\mathrm{.}9N,F_{ED}=628\mathrm{.}57,$vec$(A)=($:$32\mathrm{.}4,107,1277\mathrm{.}6$:$)N$
