Let V1 = 100/0 V,
Chapter 10, Problem 72(choose chapter or problem)
Let \(\mathbf{V}_{1}=100 \angle 0^{\circ} \mathrm{V}\), \(\left|\mathbf{V}_2\right|=140\mathrm{\ V}\), and \(\left|\mathbf{V}_1+\mathbf{V}_2\right|=120\mathrm{\ V}\). Use graphical methods to find two possible values for the angle of \(\mathbf{V}_{2}\).
