If `vecA= hati+2hatj+3hatk, vecB=-hati+hatj + 4hatk and vecC= 3hati-3hatj-12hatk`, then find the angle between the vector `(vecA+vecB+vecC) and (vecAxx vecB)` in degrees.

Explanation

To find the angle between the vectors \(\vec{P} = \vec{A} + \vec{B} + \vec{C}\) and \(\vec{R} = \vec{A} \times \vec{B}\), we will follow these steps:

### Step 1: Define the vectors
Given:
\[ \vec{A} = \hat{i} + 2\hat{j} + 3\hat{k} \]
\[
