Answer 1

Explanation:

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 =
`(1)/(2)(b_1+b_2)`

3). MN =
`(1)/(2)(18+10)`

= 14

4). MN =
`(1)/(2)(57+76)`

= 66.5

5). MN =
`(1)/(2)(AB+DC)`

7 =
`(1)/(2)(AB+10)`

14 = AB + 10

AB = 14 - 10

AB = 4

6). 15 =
`(1)/(2)[(3x+2)+(2x-2)]`

30 = 5x

x = 6
