The tension in the right cable is 525.7 N

How to determine this?

The person is in equilibrium, indicating that the net horizontal force
(\(\sum F_x = 0\)) and the net vertical force
(\(\sum F_y = 0\)) acting on them are both zero.

For the horizontal equilibrium:


\[ T_(R) \cdot \cos 48^\circ - T_(L) \cdot \cos 35^\circ = 0 \]


\[ T_(R) = \left( (\cos 35^\circ)/(\cos 48^\circ) \right) T_(L) \]

For the vertical equilibrium:


\[ T_(R) \cdot \sin 48^\circ + T_(L) \cdot \sin 35^\circ - W = 0 \]


\[ \left( (\cos 35^\circ)/(\cos 48^\circ) \cdot T_(L) \right) \cdot \sin 48^\circ + T_(L) \cdot \sin 35^\circ - mg = 0 \]


\[ T_(L) \cdot (\cos 35^\circ \cdot \tan 48^\circ + \sin 35^\circ) = mg \]


\[ T_(L) = (mg)/(\cos 35^\circ \cdot \tan 48^\circ + \sin 35^\circ) \]

Given:
\( m = 65 \, \text{kg} \), \( g = 9.8 \, \text{m/s}^2 \)

Substituting the values:


\[ T_(L) = \frac{(65 \, \text{kg}) * (9.8 \, \text{m/s}^2)}{\cos 35^\circ \cdot \tan 48^\circ + \sin 35^\circ} \]


\[ T_(L) = 429.4 \, \text{N} \]

Subsequently, for
\( T_(R) \):


\[ T_(R) = \left( (\cos 35^\circ)/(\cos 48^\circ) \right) * (429.4 \, \text{N}) \]


\[ T_(R) = 525.7 \, \text{N} \]

Therefore. the tension in the right cable is 525.7 N,
