This call can depend on your opponent a bit. Whether you think that they can raise your raise with a flush draw and top pair or not and your image at the table. If they can't raise you there and don't care about your image, then I can find a fold here considering that 75 just got there and maybe his 88's. But if you believe they can, then shove it in and pray for the best.

Hopefully for the sake of your bankroll he turns over A6 A8 A4 or AK rather than an over set or 57. So what hand did you put him on when he went all in on the turn?
It is difficult to comment without any stats or reads on your opponent. If he was tight I'd expect to see a set or 2 pair, if he is looser then 75 suited and or busted flushes comes into it. You could bet bigger on the flop...if he has an ace he is probably calling a full pot cbet, I'd go 75% minimum cbet on the flop.

second hand that you have posted where you weren't at 100 bbs at the start of the hand. this will limit your winrate over time when you get your monsters. Again flop bet is too small and says that you are afraid of the Ace. Bet more on the flop and he could well have folded his pair of 8's

Bet more on the flop. How much difference do you expect in his range to call .30 vs. say .40 to .45?

Bet high on the flop.
Another variation is controlled pot but I like your move more.
No regrets. He was just lucky on the turn.
