Graphically add the following three phasors and determine

Question

1. Given the sinusoids v₁(t) = 250 cos (ωt - 45°) V and v₂(t) = 750 sin (ωt)V, use the additive property of phasors to find v₃(t) such that v₁ + v₂ + v₃ = 0.

2. Graphically add the following three phasors and determine their sum: V₁ = 14.14 + j 14.14 V, V₂ = 10 ∠ - 60 V, V₃ = - 3.42 - j 9.40 V.
