You are welcome. I can help with more questions that you may have.

Thank you. I have one more. Circles R and Q have radii 3 and 4 respectively. They are externally tangent to each other and also are both externally tangent to larger circle P. What must be the radius of circle P so that <QRP is a right angle?
