Find angle between `vecA=3hati+4hatj " and " vecB=12hati+5hatj?`

Explanation

To find the angle between the vectors \(\vec{A} = 3\hat{i} + 4\hat{j}\) and \(\vec{B} = 12\hat{i} + 5\hat{j}\), we can follow these steps:

### Step 1: Write down the formula for the angle between two vectors
The angle \(\theta\) between two vectors can be calculated using the formula:
\[ \cos(\theta) = \frac{\vec{A} \cdot \vec{B}}{|\vec{A}| |\vec{B}|} \]
