You choose which one happens first because you can order your triggers, as you would with multiple enter the battlefield triggers or multiple death triggers.
"603.3b If multiple abilities have triggered since the last time a player received priority, each player, in APNAP order, puts triggered abilities he or she controls on the stack in any order he or she chooses. (See rule 101.4.) Then the game once again checks for and resolves state-based actions until none are performed, then abilities that triggered during this process go on the stack. This process repeats until no new state-based actions are performed and no abilities trigger. Then the appropriate player gets priority. #"

Please note that you choose the order when you put the abilities on the stack, not when they resolve. You can not reveal a card and then decide which ability it is for.
