If you cannot even start a problem of geometry - why are you in this class?

6. So in what class should I start it?(I am new in this website)

7. I addition what is $r$ supposed to be?

8. I think you did not read my explanation carefuly because I explain that AB=BC=DC=AD=X
Furthurmore there are many people in this website that solve problems even those which are too basic without directing them to the classroom help so if sending me to classroom is the only solution that you know please let other who are more generous to solve my problem ???
