Question
I need to find RT
**Find \( RT \).** The diagram provided is a circle with several lines intersecting it. To help explain the problem, here is a detailed description of the diagram: 1. **Circle**: The circle has a diameter labeled \( PQ \) and a chord \( ST \). The length of the diameter \( PQ \) is given as 13. 2. **Lines and Points**: - Point \( P \) and Point \( T \) are on the circle. - Point \( R \) is outside the circle. - Line \( RS \) intersects the circle at points \( S \) and \( T \), where \( S \) is on the circle and the segment \( RS \) has a length of 11. - Line \( RQ \) intersects the circle at point \( Q \) which is on the circle, and the segment \( RQ \) has a length of 9. - The segment \( RT \) is unknown and is denoted as \( x \). To find the length of \( RT \), we can use the Power of a Point theorem which states: \[ PA \times PB = PC \times PD \] Applying this to our circle and points \( R, S, Q, \) and \( T \): \[ (RT + TS) \times TS = (RQ + QS) \times QS \] Given the dimensions: - \( RQ = 9 \) - \( RS = 11 \) - Diameter \( PQ = 13 \) To calculate \( RT \), relevant formulas or additional information, such as the length of \( ST \) if its segments are not ambiguous with respect to the circle's points, will be needed. Please refer to the provided information and apply the appropriate geometric relations directly.
