impedance question

[matt12321]

A Capacitor of Capacitive Reactance 50 ohms, an inductor of 80ohms Inductive Reactance
and a Resistor of 40ohm are connected in series to a 200v 50 Hz supply. The impedance
of the circuit will be?

i know the that

z= square root of R squared + (xl - xc)2

but i cant seem to work this one out. if any one can help it would be much appreciated
