A graphical addition problem is solved. A diagram is included with this fully-worked solution.

##### Solution Preview

V1 = 3*sin(theta+20 degrees)

V2 = 5*sin(theta-40degrees)

Let us assume

theta+20 = phi

THerefore,

V1 = 3*sin(phi)

V2 = 5*sin(phi-60 degree)

Hence the phase difference between two volatages is ...
