Let's draw and label the situation:
- Let **T** be Thea's position on the ground.
- Let **E** be Ella's position on the ground, **6 feet closer** to the kite than Thea.
- Let **K** be the position of the kite in the air, directly above the ground (not necessarily above either girl).
- The ground is level.
Let:
- \( h \) = **vertical height** of the kite above the ground (this is what we want)
- \( d \) = **horizontal distance** from Thea to the point on the ground directly below the kite
Given:
- The angle from Thea's feet to the kite is \( 30^\circ \).
- The angle from Ella's feet to the kite is \( 45^\circ \).
- Ella is 6 feet closer to the kite horizontally than Thea, i.e., **the horizontal distance from Ella to the kite is \( d - 6 \)**.
**Let's set up the equations using right triangle trigonometry.**
---
## For Thea:
\[
\tan(30^\circ) = \frac{h}{d}
\]
\[
h = d \cdot \tan(30^\circ)
\]
---
## For Ella:
\[
\tan(45^\circ) = \frac{h}{d - 6}
\]
\[
h = (d - 6) \cdot \tan(45^\circ)
\]
But \(\tan(45^\circ) = 1\), so:
\[
h = d - 6
\]
---
## Set the two expressions for \( h \) equal:
\[
d \cdot \tan(30^\circ) = d - 6
\]
\[
d \cdot \tan(30^\circ) - d = -6
\]
\[
d(\tan(30^\circ) - 1) = -6
\]
\[
d = \frac{-6}{\tan(30^\circ) - 1}
\]
---
## Calculate \( \tan(30^\circ) \):
\[
\tan(30^\circ) = \frac{\sqrt{3}}{3} \approx 0.5774
\]
So,
\[
d = \frac{-6}{0.5774 - 1} = \frac{-6}{-0.4226}
\]
\[
d \approx \frac{6}{0.4226} \approx 14.2 \text{ feet}
\]
---
## Now, find \( h \):
\[
h = d \cdot \tan(30^\circ) \approx 14.2 \cdot 0.5774 \approx 8.2 \text{ feet}
\]
---
### **Final Answer:**
\[
\boxed{8.2\ \text{feet}}
\]
The vertical height of the kite from the ground is **about 8.2 feet**.

Let's carefully analyze the problem step-by-step:
**Given:**
- Thea and Ella are on level ground, both to the left of the kite.
- Ella is 6 feet closer to the kite than Thea.
- The angle of elevation from Thea's feet to the kite is 30°.
- The angle of elevation from Ella's feet to the kite is 45°.
- Goal: Find the vertical height \( h \) of the kite above ground.
---
### Step 1: Define variables
- \( d_T \): horizontal distance from Thea to the point directly beneath the kite.
- \( d_E \): horizontal distance from Ella to the point directly beneath the kite.
- Since Ella is 6 feet closer to the kite than Thea:
\[
d_E = d_T - 6
\]
- \( h \): vertical height of the kite (unknown).
---
### Step 2: Write equations using tangent of angles
**For Thea:**
\[
\tan(30^\circ) = \frac{h}{d_T}
\Rightarrow h = d_T \cdot \tan(30^\circ)
\]
**For Ella:**
\[
\tan(45^\circ) = \frac{h}{d_E}
\Rightarrow h = d_E \cdot \tan(45^\circ)
\]
Since \(\tan(45^\circ) = 1\), this simplifies to:
\[
h = d_E
\]
But recall:
\[
d_E = d_T - 6
\]
So:
\[
h = d_T - 6
\]
---
### Step 3: Set the two expressions for \( h \) equal
\[
d_T \cdot \tan(30^\circ) = d_T - 6
\]
Substitute \(\tan(30^\circ) = \frac{\sqrt{3}}{3} \approx 0.5774\):
\[
d_T \times 0.5774 = d_T - 6
\]
Rearranged:
\[
0.5774 d_T - d_T = -6
\]
\[
(-0.4226) d_T = -6
\]
\[
d_T = \frac{-6}{-0.4226} \approx 14.2 \text{ feet}
\]
---
### Step 4: Find the height \( h \)
\[
h = d_T \times \tan(30^\circ) \approx 14.2 \times 0.5774 \approx 8.2 \text{ feet}
\]
---
### **Final answer:**
\[
\boxed{\text{The height of the kite is approximately } \mathbf{8.2 \text{ feet}}}
\]
