    (V1-20/30°)/125 - V1/j50 + V1/j80 = 0

    (V1-20/30°)/125 + jV1/50 - jV1/80 = 0

    (V1-20/30°)/125 + (j3/400)V1 = 0

    V1(1/125 +j3/400) = 20/125 /_30°

    V1  = [20/125 /_30°]/(1/125 +j3/400) 

    V1 = [20/125 /_30°]/0.0109659/_43.15°

    V1 = 14.59 at -13.15° <<<<<<<

    No.  There are no units on the resistor. What is 'j'?   The capacitance is not given...did you make this up?

    Well that depends on the weight of the red car approximately 750m away multiplied by the temperature of the sun. Then divide this number by the square root of how many girlfriends/boyfriends you’ve had. Then add your age and minus pi. There’s your answer
