Finding voltage phasor resistance * current phasor

Homework Statement

I=75<120 deg.
R= 4k
find phasor voltage

does the 4,000 multiply the 75 only so you get

300000<120

or does it multiply 4,000 both values including the angle ?

Multiplying a complex number or phasor by a real constant changes only its magnitude. The angle remains the same.
