Question

$\Sigma {F_x} = 0$

$ \Rightarrow x + 5\cos {53^o} - y\sin {35^o} = 0$

$ \Rightarrow x + 3 - \frac{{4y}}{5} = 0 \Rightarrow 5x + 15 - 4y = 0$

Vedclass · Accepted Answer

$5,\, 10$

Vedclass · Answer

$\Sigma {F_x} = 0$

$ \Rightarrow x + 5\cos {53^o} - y\sin {35^o} = 0$

$ \Rightarrow x + 3 - \frac{{4y}}{5} = 0 \Rightarrow 5x + 15 - 4y = 0$

$\Sigma {F_y} = 0$

$10 - 5\sin {53^o} - y\cos {35^o} = 0$

$ \Rightarrow 10 - 4 - \frac{{3y}}{5} = 0$

$ \Rightarrow 6 = \frac{{3y}}{5}$

$ \Rightarrow y = 10$

$	herefore x = 5$
