Bobby goes to the local park and decides to test how high he can swing on three different swings. On the first swing, he goes 56 feet in the air, then comes back down and goes another 53 feet high. On the second swing, he goes as high as he did on the first one plus an additional 5 feet. On the third swing, he challenges himself and goes as high as he did on the second one plus an additional 34 feet. How high did Bobby swing on the third swing?
