In order to find the magnitude you have to apply the Pythagorean theorem: √(18² + 12²) = √468 = 21.6 Therefore, the magnitude of the resultant vector is 21.6
The direction is given by the formula: α = tan⁻¹(v_y / v_x) = <span>tan⁻¹(12/18) = 33.7° Therefore, the direction will be 33.7° from the x-axis.</span>
