Question 1154310
.
<pre>

In your post, in its first line, the fragment   " In ⊙ O, AC_ is tangent at B, "


and the next fragment  " and BE_ ⊥ DF_ "  are disconnected both logically and geometrically.



Therefore, as it is worded, printed, posted and presented, the problem makes no sense and can not be solved.


To be solved, the problem description must be changed to be precisely correct.
