How can I find X

[next sleet]

so, these two triangles are similar, and I need to find X, but I'm not sure how I can.

1. Ask your question and show the work you've done so far. If you've posted a screenshot of a question, specify which part you need help with.
2. Wait patiently for a helper to come along.
3. Once someone helps you, say thank you and close the thread with:

   +close
   

4. Feel free to nominate the person for helper of the week in #helper-nominations
5. Do not ping the mods, unless someone is breaking the rules. If there is a conflict amongst multiple helpers feel free to ping “Helper Mod”
6. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

try to find the value of the vertical line

this can be done through similar triangles

That's not really necessary.

i would be happy to hear your method

[placid dragon]

The side x is the hypotenuse of the smallest triangle and the short leg of the largest triangle.

[tawny granite]

that certainly also works

thank you for the insight

i didn't think of that

There are actually three similar triangles in this image.
