A weight is acted upon by three forces as shown. On the picture of the weight on the right, illustrate the addition of the vectors in the order indicated by the labels $(R^{\text{'}}=F_1+F_2,$ then $($:$R=R^{\text{'}}+F_3\}.$ Then, using your sketch as a guide, estimate the magnitude of the resultant vector $R,$ giving the answer in Cartesian vector form. To receive full credit, you must represent the addition of the three vectors graphically, "tip to tail," and show the resultant vectors $R^{\text{'}}$ and $R$ on the graph paper below. The graph paper is scaled so that $\frac{1}{4^{\text{'}\text{'}}}($one square$)$ represents $100$ N $.$
