Question

I need to find the lengths of x and y. Thanks for the help!

Answer 1

Here's the diagram:

Answer 2

please you have to apply the Talete theorem, so we can write these two proportion:
\[14:21=x:15,y:21=20:15\]
please solve those two proportion for x and y, and you will get your answers

Answer 3

do you know how to solve a proportion?

Answer 4

One second...

Answer 5

Would x = 10?

Answer 6

yes!

Answer 7

and Y = 28? But that doesn't make sense when you look at the rest of the diagram

Answer 8

y=28 that's right!

Answer 9

why not?

Answer 10

How can X (DB) be longer than side DC which is 8?

Answer 11

DC is 15

Answer 12

But the diagram shows that it's 8? How did you get 15? Thanks so much for the help!

Answer 13

I read DC=!5 from your drawing!

Answer 14

oops...DC=15

Answer 15

Oh oops! I was looking at the wrong diagram! You're right. Thanks so much!

Answer 16

Thank you!
