Hello there ,
http://img8.imageshack.us/img8/3118/circlem.jpg [Broken]
As you see the diameter = 5cm and AD = 4cm
the required is to find AB
it seems quite easy ,its just 6cm. I can solve it but when supposing that AB is a tangent (and this is not given in the problem) also i can't make use of the right angle opposite to the radius of this circle , so there must be something wrong with my answer.
so ,can u help?
Thanks in advance
