    you need to show some work before we can help.

    To give you a hint the answer it isnt a) since the diameter would be 22cm but DC is 25cm do you see why?

    Next hint is that br=bq and lines that are tangent to the circle are perpendicular to the radius drawn there so you can construct some intermediate triangles and test the other possible answers.
