Note that the 8 unit forces make an angle of 45 degrees with the horizontal. One acts at (-2, 2) and the other at (2,-2). The 7 unit forces act at (-3, 0) and (3, 0). The 12 unit forces make an angle of 30 degrees with the vertical and act at (-7, 0) and (7, 0). Scan your work and upload it here. A PDF file only please. 8 12 45 7 7 45 8 12 30
