Answer: hello your question is poorly written hence I will provide the required matrix
answer :
A =
![\left[\begin{array}{ccc}1&0&1\\0&1&1\\1&-1&0\end{array}\right]](https://img.qammunity.org/2022/formulas/mathematics/college/pzgmiia6d9lypxhmrke0gj42ln6zfq5kqc.png)
Explanation:
Given that the basis of the orthogonal complement have been provided already by you in the question I will have to provide the Matrix
The required matrix
![\left[\begin{array}{ccc}1&0&1\\0&1&1\\1&-1&0\end{array}\right]](https://img.qammunity.org/2022/formulas/mathematics/college/pzgmiia6d9lypxhmrke0gj42ln6zfq5kqc.png)
column1 = column 3 - column2
where column 3 and column 2 are the basis of the orthogonal complement of the column space of the Matrix
