To find the magnitude of the resultant vector A+B+C, first convert each vector into its component form using trigonometric functions based on their angles. Vector A has components of approximately 7.34 m east and 3.43 m north. Vector B, pointing west of north, has components of about -0.86 m east and 2.34 m north, while Vector C, pointing west of south, results in approximately -2.49 m east and -1.67 m south. After summing the components, the resultant vector can be calculated, yielding a final magnitude. Understanding vector addition and component breakdown is crucial for solving such problems effectively.
