![### Problem Statement
Find the tension in each of the three cables (in N) supporting the traffic light if it weighs \(4.67 \times 10^2\) N.
### Diagram Explanation
The diagram illustrates a traffic light supported by three cables:
1. **Cable 1**: Makes an angle of \(41.0^\circ\) with the horizontal.
2. **Cable 2**: Makes an angle of \(63.0^\circ\) with the horizontal.
3. **Cable 3**: Hangs vertically downward and directly supports the traffic light.
The weight of the traffic light, \(w\), is given as 467 N, directed downwards.
### Necessary Calculations
To compute the tensions \(T_1\), \(T_2\), and \(T_3\) in the cables:
1. **Equilibrium in the vertical direction**:
- Summation of vertical components of the tensions \(T_1\) and \(T_2\) should equal the weight supported by them minus \(T_3\).
2. **Equilibrium in the horizontal direction**:
- The horizontal components of tensions \(T_1\) and \(T_2\) must balance each other.
#### Equations
- \(T_1 \cos(41.0^\circ) + T_2 \cos(63.0^\circ) = 0\)
- \(T_1 \sin(41.0^\circ) + T_2 \sin(63.0^\circ) = 467 \text{ N}\)
- \(T_3 = \text{component supporting the vertical weight}\)
### Input Fields for Solution
\[ T_1 = \boxed{} \text{ N} \]
\[ T_2 = \boxed{} \text{ N} \]
\[ T_3 = \boxed{} \text{ N} \]](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F6b165613-2027-4238-9c7e-a40fd74e53eb%2Feb80527e-d34d-4234-ba3f-a6cab821bf94%2Fcqphhaj.png&w=3840&q=75)
