Saved? From what and how. Contrary to the above answer tomatoes can survive way above 75.2F. I think David looked up ideal conditions - and this would be for average temps probably. Tomatoes can tolerate temps into the 100's - and do here. They drop their blossoms, but fruits are usually OK. I suspect that you stressed the plant in some other way - like transplanting it, or moving it to a much sunnier spot. I also see some yellow and brown leaves and that could indicate a blight. I would pick the tomatoes and let them ripen indoors. Let the plant recover, then produce more. I don't think there is any hope for those tomatoes if you leave them on the vine.
