Write the complement of each of the following angles:
`90^(@)`

Answer

To find the complement of the angle \(90^\circ\), we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definition of Complementary Angles**:
Complementary angles are two angles whose sum is \(90^\circ\).

2. **Identify the Given Angle**:
The angle given in the question is \(90^\circ\).

3. **Set Up the Equation**:
Let \(x\) be the complement of \(90^\circ\). According to the definition, we have:
\[ 90^\circ + x = 90^\circ \]

4. **Solve for \(x\)**:
To find \(x\), we rearrange the equation:
\[ x = 90^\circ - 90^\circ \]
\[ x = 0^\circ \]

5. **Conclusion**:
Therefore, the complement of \(90^\circ\) is \(0^\circ\).

### Final Answer:
The complement of \(90^\circ\) is \(0^\circ\).
