Segment AB is tangent to circle O at B, segment AB and segment ADC intersect at A and chord BC is congruent to chord CD. If the measure of arc BD = 60 and segment BC = 8, find the length of tangent segment AB.

This question is found in the chapter titled SOLVING TRIANGLES THAT INTERSECT CIRCLES AND THE LAW OF SINES.

I understand that BC and the measure of angle C = 1/2 times the measure of arc BD, which = 1/2 of 60 = 30.

Where do I go from there?

No help whatsoever. Thanks for nothing. Do you always act like little kids?
 
Relax, That's code for "We can't translate the problem statement."

I'm not getting it, either. "segment ADC" loses me. Normally, a segment wouldn't be named with three points. There is no way to tell which way things are pointing. It's just not clear enough from the brief verbal description. A picture would go a long way.
 
The point is, I think that this person mathxyz is getting ALL his/her homework done without much or any personal effort.
I think that is not the purpose of the HELP sites.
 
Hey

I show my work depending on the level of difficulty of the question.
I like doing my own work. I post problematic questions. If I do not understand the question at all, there's no work to show.
