Answer: EB = 20

Explanation:

Hi there. I'm sending you a picture of how the triangle looks like with the sides identified by their values. Given that AB | DE, meaning that they are proportional, then we can assume this:

- AD | EB

- CD | CE

We can also set this ratio up:


(15)/(EB) = (21)/(28)

Cross multiply the proportion and then divide, to find the value of EB:


15 * 28 / 21=20

Side EB should be equal to 20.
