Question

Plssssss help math plssssss last question

Answer 1

This question is based on parallel lines proportionality that states if three or more lines intersect two traversals, then they cut the traversals proportionally.

In this case, the formula becomes:

`(DE)/(EF)=(LM)/(MN)`

`(2x)/(3x-5)=(4)/(5)`

`10x=12x-20`

`2x=20`

`x=10`

The value of x = 10

To find the proportions or DE and EF,

DE = 2x = 2*10=20

EF = 3x-5 = 30-5 = 25

If we find DE/EF, it becomes 20/25 or 4/5
