Answer:

x = 8

Step-by-step explanation:

$\sf If\:\: \overline{NO} \parallel \overline{KJ}\:\:then\:\: \triangle LNO \sim\triangle LKJ$

Therefore:

$\implies \sf \overline{LN} : \overline{LO} = \overline{LK} : \overline{LJ}$

$\implies (x-3):(x-4)=(x-3)+(x+2):(x-4)+x$

$\implies \dfrac{x-3}{x-4}=\dfrac{2x-1}{2x-4}$

$\implies (x-3)(2x-4)=(2x-1)(x-4)$

$\implies 2x^2-10x+12=2x^2-9x+4$

$\implies -10x+12=-9x+4$

$\implies 12=x+4$

$\implies x=8$

Answer:

AC = 13 units

Step-by-step explanation:

A(0 , -4) ; c(5 , 8)

Distance = $\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

$= \sqrt{(5-0)^{2}+(8-[-4] )^{2}} \\\\\\= \sqrt{5^{2}+(8+4)^{2}} \\\\\\=\sqrt{5^{2}+12^{2}}\\\\= \sqrt{25 + 144}\\\\= \sqrt{169} = 13 \\\\\\$
