Answer: EB = 20

Step-by-step 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:

$\frac{15}{EB} = \frac{21}{28}$

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

$15 * 28 / 21=20$

Side EB should be equal to 20.

Step-by-step explanation:

CD : DA = CE : EB

21 : 15 = 28 : EB

21*EB = 28*15

EB = 28*15/21 = 20

Ne4ueva [31]

It rained 1 and 4/10 centimeters. You have to first figure out what adds up to 14, which is 1/10. Then you add 1 to get 15 and 3/10 to get 15 3/10.
