Addition of HBr to a double bond with an ether (?OR) substituent occurs region specifically to give

Question:

Addition of HBr to a double bond with an ether (?OR) substituent occurs region specifically to give a product in which the ?Br and ?OR are bonded to the same carbon. Draw the two possible carbocation intermediates in this electrophilic addition reaction, and explain using resonance why the observed product is formed.
