Answer:

x = 12

Step-by-step explanation:

The line joining the mid points of the non- parallel sides is parallel to the parallel sides and is equal to half the sum of the parallel sides, hence

5x - 20 = \frac{1}{2}(2x + 6 + 4x + 2)

            = \frac{1}{2}(6x + 8) ← distribute, giving

5x - 20 = 3x + 4 ( subtract 3x from both sides )

2x - 20 = 4 ( add 20 to both sides )

2x = 24 ( divide both sides by 2 )

x = 12
