The answer to your question is: midsegment = 35 units

Step-by-step explanation:

Use the Thales' theorem

                          43( 3x + 55) = 86( 6x + 5)

                          129x + 2365 = 516x + 430

                          129x - 516x = 430 - 2365

                          -387x = -1935

                           x = -1935 / -387

                           x = 5

Midpoint length = 6(5) + 5

                           = 30 + 5

                          = 35 units
