The magnitude of the resultant vector A+B+C can be calculated by first converting each vector into its component form. Vector A, with a magnitude of 8.10 m at 25.0° north of east, can be expressed as A_x = 8.10 * cos(25.0°) and A_y = 8.10 * sin(25.0°). Vector B, at 2.50 m and 20.0° west of north, translates to B_x = -2.50 * sin(20.0°) and B_y = 2.50 * cos(20.0°). Vector C, at 2.90 m and 35.0° west of south, is represented as C_x = -2.90 * cos(35.0°) and C_y = -2.90 * sin(35.0°). The resultant vector's components are then summed to find the total magnitude.
