Answer 1

x=12

Explanation:

Answer 2

x = 12

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 =
`(1)/(2)`(2x + 6 + 4x + 2)

=
`(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
