Using the similarity between triangles, we can determine the value of x. By comparing the corresponding sides of the triangles, we can see that the ratio of the sides in the smaller triangle to the sides in the larger triangle is the same. In this case, the ratio of the sides is 4:9. Since the side length of the larger triangle is 9, we can set up a proportion: 4/9 = x/15. Cross-multiplying, we get 9x = 60. Dividing both sides by 9, we find that x = 6. Therefore, the value of x is 6.
