**Geometry in Action: Tents and Triangles**

**27. Use Structure**
The front of the tent below is shaped like an equilateral triangle.

a. **Question:** What is the side length of the triangle? Round to the nearest tenth of a foot.

b. **Explanation:** Explain the method you use to calculate the length.

*Diagram Description:* 
The tent is depicted with a schematic showing an equilateral triangle. One side is labeled as 5 ft (feet) indicating the height from the base to the peak.

---

**28. Look for Relationships**
For a crane to lift the beam shown below, the beam and the two support cables must form an isosceles triangle with height \( h \). If the distance between the cables along the beam is 18 ft and the height \( h \) is the total length of the beam, what is the total length of the cables?

*Setting Description:* 
This scenario includes a forest and a campfire, providing a real-life context where understanding the relationships between different triangle types is crucial.

*Visual Elements:*
- **Tent Shape:** Appears as a triangular front with a height line that is 5 ft.
- **Beam Context:** Imagined scenario involving a crane and an isosceles triangle that must be analyzed in context.

This educational module invites students to engage deeply with geometric concepts, applying structure and relational thinking to solve practical problems.
