$\huge{\tt\red{Answer}}$

$\tt\orange{Given}$

$\bullet\:\tt {Seg\: OL\: is\: perpendicular\: to\: seg\: AB.}\\\\ \bullet\:\tt {AB \:=\: 6cm}\\\\\bullet\:\tt {OA\:=\:5cm}$

$\tt\orange{To \:Find}\\\\\tt Seg\:OL\:=\:?$

$\tt\orange{Solution}$

$\bf A \:segment\:drawn\: perpendicular\: to\: the\: chord \:bisects\: the\: chord.$

$\therefore\tt{ AL\:=\:BL}\\\\\tt AL\:=\:\dfrac{AB}{2}\\\\\tt{ Consider\: the\: \vartriangle OAL}\\\\\therefore \tt \angle OLA\:=\:90°\\\\$

$\tt AO^2\:=\:AL^2\:+\:OL^2\\\\\rightarrow \tt 5^2\:=\:3^2\:+\:OL^2\\\\\rightarrow\tt 25\:=\:9\:+\:OL^2\\\\\rightarrow\tt 25\:-\:9\:=\:OL^2\\\\\rightarrow\tt 16\:=\:OL^2\\\\\rightarrow\tt \sqrt{16}\:=\:OL\\\\\Longrightarrow\bf{\pink{4\:=\:OL}}$
