RLC Circuit: Calculate R Given V,f,P

[Maxamillion00]

RLC Circuit - Given V,f,P find R?
You have an inductor plugged into a 100 V AC source with a frequency of 50 hertz. There is a power of 6 watts and this can modeled as an LR circuit with R being the resistance from the Inductor. Calculate R.

This is just an RL circuit... how did you attempt the problem?
