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:

$\frac{DE}{EF}=\frac{LM}{MN}$

$\frac{2x}{3x-5}=\frac{4}{5}$

$10x=12x-20$

$2x=20$

$x=10$

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
