Learning Goal: Three structural angles act on the support plate as shown in (Figure 1). The magnitudes of two of the forces are $F_1=9\mathrm{kN}$ and $F_2=9\mathrm{kN}$. Calculate the horizontal component of the resultant force due to ${\mathbf{F}}_1$ and ${\mathbf{F}}_2$. Express your answer to three significant figures with appropriate units. Part B What is the required magnitude for ${\mathbf{F}}_3$ ? Express your answer to three significant figures with appropriate units. Figure 1 of 1 Part C Calculate the vertical component of the resultant force. Express your answer to three significant figures with appropriate units. Express your answer to three significant figures with appropriate units. Learning Goal: Three structural angles act on the support plate as shown in (Figure 1). The magnitudes of two of the forces are $F_1=9\mathrm{kN}$ and $F_2=9\mathrm{kN}$. Part D Calculate the magnitude of the resultant force. Express your answer to three significant figures with appropriate units. Calculate the direction of the resultant force. Give the angle $?$ between the force and the positive $x$-axis. Express your answer to three significant figures with appropriate units.
