Transcribed Image Text:In the diagram, a straight line labeled CD is shown, which is tangent to two circles, labeled A and B. Circle A is larger and is tangent to circle B, which is smaller. Both circles are in contact with each other and the line CD at their outer edges. The point where line CD is tangent to circle A is labeled D, and the point where it is tangent to circle B is labeled C. The centers of the circles are connected by radii to the points of tangency.
The text below the diagram reads:
"In the diagram, CD is tangent to circles A and B, and the circles are tangent to each other. Answer the following:"
![12) If CD = 15 and AB = 17 and CB = 6, find AD [Input Box]
This question prompts the student to use given measurements of line segments in a geometric figure to find the length of another segment. Based on the information:
- CD = 15
- AB = 17
- CB = 6
The goal is to find the length of segment AD. The problem likely involves addition and subtraction of line segments, depending on their arrangement in a geometric context. There are no graphs or additional diagrams provided.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F339e3a68-4ac7-4deb-94f2-79c110cd0591%2F282d6a5c-9d54-4914-9947-203546d86c73%2F9ychwld_processed.png&w=3840&q=75)
