Please solve this question 23 . I f A = i ^ + 2 j ^ + 3 k ^ , B = - i ^ + j ^ + 4 k ^ a n d C = 3 i ^ - 3 j ^ - 12 k ^ , t h e n f i n d t h e a n g l e b e t w e e n t h e v e c t o r s A + B + C a n d A × B .

$23 . I f A = \hat{i} + 2 \hat{j} + 3 \hat{k}, B = - \hat{i} + \hat{j} + 4 \hat{k} a n d C = 3 \hat{i} - 3 \hat{j} - 12 \hat{k}, t h e n f i n d t h e a n g l e b e t w e e n t h e v e c t o r s (A + B + C) a n d (A \times B) .$
