Question

answer me soon pls. I want the answer step by step

Answer 1

HEY... HERE IS YOUR IS ANSWER...


let EF be x,
in triangle OEC,
OC^2 = CE^2 + OE^2
13^2 = 5^2 + OE^2
169 = 25 + OE^2

$\sqrt{144}$
12 = OE//


Also, in triangle OFA,
OA^2 = OF^2 + AF^2
13^2 = OF^2 + 12^2
169 = OF^2 + 144
25 = OF^2
OF = 5


X = OE - IF
X = 12 - 5
X = 7//
hence, found


HOPE THIS WOULD HELP YOU
