Question

Find each value

ED=
AB=

Answer 1

ED = 57 , AB = 19

Explanation:

the midsegment FC is half the sum of the parallel bases , that is

`(AB+ED)/(2)` = FC

`(4x+3+18x-15)/(2)` = 38 ( multiply both sides by 2 )

22x - 12 = 76 ( add 12 to both sides )

22x = 88 ( divide both side by 22 )

x = 4

then

ED = 18x - 15 = 18(4) - 15 = 72 - 15 = 57

AB = 4x + 3 = 4(4) + 3 = 16 + 3 = 19
