Find the maximum weight of the lamp if the cords cannot support more than 20 lbf. Also find θ.
---
### Diagram Description:
The diagram shows a suspended lamp attached by three cords. The setup includes:
- A point E where cord BE (30 degrees from horizontal) is connected to the left wall.
- A point D where cord CD, forming angle θ from horizontal, is connected to the right wall.
- The lamp is supported by a vertical cord at point A.
- Horizontal distance CE = 6 feet.
- Vertical line from point B to A is labeled with angle 60 degrees from horizontal.

**Answer:**
θ = 18.4°
W = 15.8 lbf
