Answer:
DE=15 and AB=6
Step-by-step explanation:
Both Triangles are Similar. When looking at the length of AC, it is 3x smaller than CE. So we know that the triangle ABC is 3x smaller than CDE. Since we know that we can see that DE is 15 since it is 3x Larger than 5. We also know that AB is 6 since it is 3x smaller than 18
