Learning Goal: As shown, three forces act on the tip of a pole. F--60i+105 j +25 k lb. F-150 lb and forms the following angles with the x, y, and z axes, respectively: -51.2, 8-66.6, and 7-132.1-901b, forms the angle -26 with the z axis, and forms the angle 9-21 between the xaxis and the projection of F's in the zy plane. Find the resultant of adding F, and F. Express your answer in component form. Express your anciers, separated by commas, to three significant figures.
