1. In Figure 8, each of the circles with centers A, B, and C is tangent to theother two. If AB = 10, AC = 14 and BC = 18, find the radius of each circle. A B Q A Figure 8 Figure 9 2. The radii of the two circles in Figure 9 are 3 and 8, and the distance between their centers are 13. Find the length o their common external tangent.
