$\sf{\large{\underline{\boxed{\pink{\mathsf{♡ HELLO ♡}}}}}}$

$\green{\large\underline{\underline\mathtt{given :-}}}$ AD =10cm,AE =8cm,BC =18cm,angle ABC =90.

Triangle ADE is similar to triangle ACB

So, AD/AC = AE/DE =AB/BC

10/AC = 8 /DE = 10+DB /18

AC =180/10 +X

$ac {}^{2} = (10 + x) {}^{2} + 18 {}^{2}$

$(180 \div 10 + x) = (10 + x) {}^{2} + 18 {}^{2}$

8/6 = 10 +DB /18

24 = 10 +DB

${\boxed{DB = 14}}$
