Solve this puzzle for me. It's a pair of drawings. In the drawing on the left there's a table with a cat sitting on top of it, and a turtle sitting on the floor under the table. There's also a large curly brace spanning from the head of the cat to the back of the turtle which has "170 cm" written next to it. The drawing on the right is much the same, but the positions of the cat and the turtle are swapped. The brace still spans from the back of the turtle to the head of the cat, but has "130 cm" written next to it. The question is: How tall is the table?
