Those are the correct formulas for calculating reactive impedance, but the impedance figures given should not be considred the same as resistance. Resistance is a dissipative load whereas reactance is a reflective load. Pure reactance doesn't actually absorb power and do work; Instead, it reflects the energy back. This property is described by considering reactive impedance to be out of phase with resistance by 90^o; It is expressed as an imaginary term with the value i or the square root of -1. As such, reactances must be combined as vectors.

You might want to get an electronics textbook and study AC circuits and reactive impedance. That will shed some light on this for you.
