Hey all, I've tried searching through the forum but cannot find anything relating to this question. It is for distinction grade so I'm struggling.

The question reads:

Voltages V1 and V2, represented by the equations V1=30sin(Θ+60°) and V2=50sin(Θ+45°) volts are added together as Vr=V1+V2.

I need to use compound formula to simplify this and add them together.

I am okay with that, but I have only done it with sin (A+B) = sinA cosB + cosA sinB.

What confuses me is the 30+ and the 50+ before the sin.

Any help appreciated.

Dan
