Make all obvious simplifications.
![**Transcription:**
The points \( A, B, C, D, E, F, G, \) and \( H \) are the eight corners of a rectangular box. \( ABCD \) is its horizontal base, and it is a square whose edges are 1 unit each. \( AE, BF, CG, \) and \( DH \) are all vertical lines of length 2. Find angle \( \angle EBH \). [Hint: the given information allows you to find the coordinates of the points, so that you can use three-dimensional vectors. Also, if you do not have a calculator, you may just give the cosine of angle \( \angle EBH \).]
**Diagram Explanation:**
The diagram depicts a rectangular box positioned within a three-dimensional \( xyz \) coordinate space. Here are the details:
- The base of the box is the square \( ABCD \) lying on the \( xy \)-plane. Each side of the square is 1 unit in length.
- The vertices \( A, B, C, \) and \( D \) are connected to the opposite vertices \( E, F, G, \) and \( H \) respectively, by vertical lines. These lines represent the height of the box, each measuring 2 units.
- The illustration also shows the vectors \( \overrightarrow{EB} \) and \( \overrightarrow{BH} \) forming the angle \( \angle EBH \) that needs to be determined.
- The \( x \), \( y \), and \( z \) axes are marked to indicate the orientation in three-dimensional space, with \( z \) representing vertical height.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F7c560a1a-db76-4fd0-82f5-78bd443b8157%2F2a9e02cc-fea2-406a-aef8-555153b93564%2Fhcw50w_processed.jpeg&w=3840&q=75)
