The figure below shows a bird feeder that weighs 190.5 N. The feeder is supported by a vertical cable, which is in turn tied to two cables, each of which is attached to a horizontal post. The left cable makes a 60° angle with the post, while the right cable makes a 30° angle. What is the tension in each cable (in N)? 60° 30

Question
The figure depicts a bird feeder weighing 190.5 N, suspended by a vertical cable tied to two additional cables attached to a horizontal post. One cable forms a 60° angle with the post, and the other forms a 30° angle. The task is to determine the tension in each cable (in N).

**Diagram Explanation:**

- **Bird Feeder**: Labeled as "Bird food" and suspended beneath the cables.
- **Cables**:
  - **Left Cable**: Forms a 60° angle with the vertical post.
  - **Right Cable**: Forms a 30° angle with the vertical post.
  - **Vertical Cable**: Supports the feeder directly from above.

**Tension Values Input:**
- **Left Cable**: Incorrect input example - 190.5 N
  - Error Message: The left cable should not use 30.0° for both angles. It is specified to use 60.0° for the left cable.
- **Right Cable**: Incorrect input example - 85.35 N
  - Guidance: Assess the forces on the feeder, identify the tension in the vertical cable, and analyze the forces at the junction of the cables.
- **Bottom Cable**: Incorrect input example - 147.8 N
  - Guidance: Determine the forces acting on the feeder using Newton's second law.

**Additional Text:**
- "Need Help? Read it" - Suggests a guidance link or instruction text.

This image is part of an educational problem illustrating equilibrium and tension in physics, encouraging the application of Newton’s laws and trigonometry to solve for the unknown tensions in the cables.
