Determine the magnitude of the vector sum $\mathbf{V}={\mathbf{V}}_1+{\mathbf{V}}_2$ and the angle ${\theta }_x$ which $\mathbf{V}$ makes counterclockwise from the positive $x$-axis. Complete both graphical and algebraic solutions. You will have to draw an accurate figure for the graphical solution. Answers: ${\theta }_x=$ - $V=$ units
