Question
## Finding the Height \( h \) of the Triangle

### Problem Statement:
You are tasked with finding the height \( h \) as indicated in the provided figure.

### Figure Description:
The image depicts a right triangle with the following information:
- One side (base) is labeled as \( 895 \).
- One angle adjacent to the height \( h \) is marked as \( 20.2^\circ \) (α).
- Another angle adjacent to the same base segment and opposite \( h \) is \( 56.8^\circ \).

The angle measurements imply that the triangle in the image is a right-angled triangle where \( α + β + 90^\circ = 180^\circ \), with \( 56.8^\circ \) being the complementary angle to the smallest one within the triangle's configuration.

### Calculation:

You need to find \( h \). To proceed, we utilize trigonometric relationships:

For the given angle \( α = 20.2^\circ \):
\[ \tan(\alpha) = \frac{h}{\text{base}} \]
Plugging in the known values:
\[ \tan(20.2^\circ) = \frac{h}{895} \]
\[ h = 895 \times \tan(20.2^\circ) \]

Using a calculator to find \( \tan(20.2^\circ) \):
\[ \tan(20.2^\circ) ≈ 0.368 \]

\[ h = 895 \times 0.368 ≈ 329 \]

Round \( h \) to the nearest integer:
\[ h ≈ 329 \]

### Result:
\[ h = 329 \]

Ensure you round your answer to the nearest integer as stipulated.
