Answer:
The Length of DB is 28.
Explanation:
The question states that the ratio from AC : DE is 3:2 which means, essentially, that Triangle DBE is 2/3 of triangle ABC's size due to the fact that they are comparing the heights of AC and DE and stating that AC is 1/3 taller than DE. So if DBE is 2/3 of the size of ABC, that means that you would take the overall length of AB and divide that by three, and then multiply that sum by 2 in order to get the length of DB, which is 28.
