We know that the midsegment connects the midpoints because it divides each side into equal parts.
We also know that x+2 and 6x+1 are parallels because the midsegment connects midpoints, which means it's parallel to the third side.
Let's call one side 2y and each part as y. We can use the following proportion
Now, we solve for x.
Hence, x = 0.75.
