Three cables are used to tether a balloon as shown in

the figure CBL$-655.$ Knowing that the balloon exerts a $1000$ N vertical

force, and the wind exerts a $100$ N force along positive x$-$direction

both acting at point A$.$

$16.$ Which of the following most nearly gives the force at cable

AB$,$ in N$?$

A$.247\mathrm{.}67$ B$.294\mathrm{.}84$ C$.458\mathrm{.}97$ D$.436\mathrm{.}35$

$17.$ Which of the following most nearly gives the force at cable

AD$,$ in N$?$

A$.247\mathrm{.}67$ B$.436\mathrm{.}35$ C$.546\mathrm{.}39$ D$.294\mathrm{.}84$

$18.$ Which of the following most nearly gives the force at cable

AC$,$ in N$?$

A$.294\mathrm{.}84$ B$.546\mathrm{.}39$ C$.458\mathrm{.}97$ D$.247\mathrm{.}67$

SITUATION $6$: Three forces P$1,$ P$2,$ and P$3$ are acting on a semi$-$circul
