10. Centipedes and three-headed dragons. In a certain herd of centipedes and three-headed dragons, there are a total of 26 heads and 298 legs. Each centipede has one head. How many legs does a three-headed dragon have?
10.Note: 1. the number of heads of dragons is divisible by 3, and the number of centipedes cannot exceed 7 (otherwise, there would be more than 298 legs), so the number of centipedes is either 2 or 5. 2. If there are 2 centipedes, then there are 8 dragons, and each dragon would have $\frac{218}{8}$ legs, which is impossible. 3. If there are 5 centipedes, then there are 7 dragons, and thus each dragon has 14 legs.
