If the flop was an all-in bet, you would likely have the necessary 30% equity to call.

But it's a bad reverse implied odds situation. A halfway decent/aggressive villain is going to value bet you to death with his AA/KK/AK and the occasional semi-bluff that hit (e.g. 89o) and he's going to push you off the hand at least some of the time when he has air. What's the plan when he fires a blank turn?
