To estimate the height of the mountain, we can use trigonometric principles. Let's define the problem mathematically:

Setup:

1. Let the height of the mountain be $h$.
2. Let the distance from the initial point of observation to the base of the mountain be $d$.
3. At the initial point, the angle of elevation is $32^\circ$, and 1000 feet closer to the mountain, the angle of elevation is $34^\circ$.

Using the tangent function: $\tan(\theta) = \frac{\text{opposite}}{\text{adjacent}}$

From the two observations, we can write: $\tan(32^\circ) = \frac{h}{d} \quad \text{and} \quad \tan(34^\circ) = \frac{h}{d - 1000}$

Step 1: Express $d$ in terms of $h$ from the first equation:

$d = \frac{h}{\tan(32^\circ)}$

Step 2: Substitute $d$ into the second equation:

$\tan(34^\circ) = \frac{h}{\frac{h}{\tan(32^\circ)} - 1000}$

Simplify: $\tan(34^\circ) = \frac{h}{\frac{h \tan(32^\circ) - 1000 \tan(32^\circ)}{\tan(32^\circ)}}$

Multiply through by $\tan(32^\circ)$: $\tan(34^\circ) \cdot (h \tan(32^\circ) - 1000 \tan(32^\circ)) = h \tan(32^\circ)$

Distribute: $h \tan(34^\circ) \tan(32^\circ) - 1000 \tan(34^\circ) \tan(32^\circ) = h \tan(32^\circ)$

Rearrange terms to isolate $h$: $h (\tan(34^\circ) \tan(32^\circ) - \tan(32^\circ)) = 1000 \tan(34^\circ) \tan(32^\circ)$

Factor $h$ out: $h = \frac{1000 \tan(34^\circ) \tan(32^\circ)}{\tan(34^\circ) \tan(32^\circ) - \tan(32^\circ)}$

Step 3: Calculate the height numerically:

Using $\tan(32^\circ) \approx 0.6249$ and $\tan(34^\circ) \approx 0.6745$: $h = \frac{1000 \cdot 0.6745 \cdot 0.6249}{(0.6745 \cdot 0.6249) - 0.6249}$

$h = \frac{1000 \cdot 0.4214}{0.4214 - 0.6249}$

$h = \frac{421.4}{0.0496} \approx 8497 \, \text{feet.}$

Final Answer:

The height of the mountain is approximately 8,497 feet.
