From phasor addition, we get that;
VT= √(40^2+20^2) = 44.72V.
VT= √(40^2+20^2) = 44.72V.

Please explain me, how it is declared?

It's RMS value so root (20^2+40^2) =45. Here 20 and 40 are average values.

C will cause a phase shift between voltage and current. Therefore the voltage across the capacitor will lag that current by 90°
vG = (vR^2 + vC^2)/2 = 45v
vG = (vR^2 + vC^2)/2 = 45v

It's RMS vslue so root(20^2+40^2)=45 . Here 20 and 40 are avg values.

(20^2 + 40^2)^(.5)= 45
