Two vectors have magnitudes `6` and `8` units, respectively. Find the magnitude of the resultant vector if the angle between vectors is (a) `60^(@)` (b) `90^(@)` and ( c ) `120^(@)`.

Explanation

To solve the problem of finding the magnitude of the resultant vector for the given angles between two vectors with magnitudes 6 and 8 units, we will use the formula for the magnitude of the resultant vector:

\[ R = \sqrt{A^2 + B^2 + 2AB \cos(\theta)} \]

where:
- \( R \) is the magnitude of the resultant vector,
