Determine the phase angle and power factor

111000123:

when R1 = 75ohms
L1 = 80mH
C1 = 47uF
V1 = 80V
F1 = 100Hz

forgot the symbols

V1=U _R1+U _L1+U _C1

X _L1 = w * L1 = 100Hz * 2pi * 80mH = 50.26548245743669Ohm
X _C1 = 1/(w * C1) = 1/(2*pi*100Hz*47uF) = 33.86275384933943Ohm
X=X _L1-X _C1 = 50.26548245743669Ohm-33.86275384933943Ohm = 16.40272860809726Ohm

Phase Angle:
phi = arctan( X/R ) = arctan( 16.40272860809726Ohm/75Ohm ) = 12.33651995704072075419Degree

Power Factor:
delta = cos( phi ) = cos( 12.33651995704072075419 ) = 0.97690959179005
