Answer:

x = 6

y = 13

Step-by-step explanation:

since DE and JK are congruent, they are both 18

to find 'y':

3y - 21 = 18

3y = 39

y = 13

DF and JL are diagonals that are congruent so:

9x - 23 = 7x - 11

2x = 12

x = 6

$\frac{n}{5} = \frac{72}{8} \\ \\ \frac{n}{5} = 9 \\ \\ n = 9 \times 5 \\ \\ n = 45 \\ \\$

The final result is: n = 45.

---------

$\frac{9}{n} = \frac{4}{18} \\ \\ \frac{9}{n} = \frac{2}{9} \\ \\ 9 = \frac{2}{9} n \\ \\ 9 = \frac{2n}{9} \\ \\ 9 \times 9 = 2n \\ \\ 81 = 2n \\ \\ \frac{81}{2} = n \\ \\ n = \frac{81}{2} \\ \\$

The final result is: n = 81/2 or n = 40.5.
