Find out the angle made by `vecA= hati-hatj+hatk` vector from X, Y and Z axes respectively.

Explanation

To find the angles made by the vector \(\vec{A} = \hat{i} - \hat{j} + \hat{k}\) with the X, Y, and Z axes, we can use the concept of the dot product. The dot product of two vectors can be expressed in terms of the angle between them.

### Step-by-Step Solution:

1. **Identify the vector and its components**:
\[ \vec{A} = \hat{i} - \hat{j} + \hat{k} \]
