QUESTION: Can you explain ,How the answer is 100 Volt.
Answer voltage total = vr + jvxl - jvxc = 70 + j70 -j100 = 70 - j30 = 76.16v at angle of -23.2 degrees.
The above is the scientific answer.
vr = voltage across resistor
jvxl = voltage across inductor
jvxc = voltage across capacitor
It is frequency dependent; I assume frequency is not changed in your example.
