As per midsegment theorem of a trapezoid,

Segment joining the midpoints of the legs of the of the trapezoid is parallel to the bases and measure half of their sum.

Length of midsegment = $\frac{1}{2}(b_1+b_2)$

3). MN = $\frac{1}{2}(18+10)$

= 14

4). MN = $\frac{1}{2}(57+76)$

= 66.5

5). MN = $\frac{1}{2}(AB+DC)$

7 = $\frac{1}{2}(AB+10)$

14 = AB + 10

AB = 14 - 10

AB = 4

6). 15 = $\frac{1}{2}[(3x+2)+(2x-2)]$

30 = 5x

x = 6
