How do I solve the length of AC?

Crank

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

∆ABC and ∆ADE are similar triangles.

Thus ;

$\frac{AD}{AC} = \frac{DE}{BC} = \frac{AE}{AB} \\$

So :

$\frac{5}{3 + 2x} = \frac{4}{8} \\$

$\frac{5}{3 + 2x} = \frac{1}{2} \\$

Inverse both sides

$\frac{3 + 2x}{5} = \frac{2}{1} \\$

$\frac{2x + 3}{5} = 2 \\$

Multiply sides by 5

$5 \times \frac{2x + 3}{5} = 5 \times 2 \\$

$2x + 3 = 10$

Thus ;

$AC = 2x + 3 = 10$

$AC = 10$

Done...
