It seems that there may be some information missing from the question, as it is not clear what "circle 0" refers to. Additionally, the values provided for "an" and "so" are not clear.
To calculate the length of the radius, we would need more information, such as the length of the tangent line or the position of point B in relation to the circle.
Please provide more information or clarify the given values for a more accurate answer.
AB is tangent to circle 0 and B the diagram is not to show if an =9 and so= 21.6
