### Problem Breakdown:

We are tasked with finding the possible values of \(x\) such that the perimeter of the triangle is less than 28 feet.

#### **Step 1: Formula for the perimeter of a triangle**
The perimeter of a triangle is the sum of the lengths of all its sides. For this triangle:
\[
\text{Perimeter} = 7 + 7 + x
\]
\[
\text{Perimeter} < 28
\]

#### **Step 2: Setting up the inequality**
Substituting the expression for the perimeter:
\[
7 + 7 + x < 28
\]
\[
14 + x < 28
\]

#### **Step 3: Solving for \(x\)**
\[
x < 28 - 14
\]
\[
x < 14
\]

#### **Step 4: Ensuring \(x\) satisfies the triangle inequality**
In any triangle, the sum of the lengths of any two sides must be greater than the length of the third side. Applying this rule:
1. \(7 + 7 > x \Rightarrow x < 14\) (this matches the condition above).
2. \(7 + x > 7 \Rightarrow x > 0\).

Thus, \(x\) must satisfy:
\[
0 < x < 14
\]

### Final Answer:
The possible values of \(x\) are:
\[
0 < x < 14
\]

Let me know if you'd like a deeper explanation or additional examples! Here are five related questions you can explore:

1. What is the significance of the triangle inequality rule in geometry?
2. How do you approach solving inequalities with multiple constraints?
3. What are other shapes where perimeter conditions can be used to find unknown lengths?
4. How would the solution change if the perimeter were a fixed value instead of an inequality?
5. How do you verify if a given value of \(x\) satisfies all conditions for a triangle?

**Tip:** Always check the triangle inequality when solving problems with unknown side lengths to ensure a valid triangle.
