I don't understand the question. You have only one missing length for two triangles?
I do note that the ratio of sides in the two cases is
2:3:(1/3)x
2:3:4
Just considering triangle 1, x could be anything less than 45 (bonus question: why?).
Maybe you want x so that the two triangles will be the same shape - same angles. If so, I think I've given you a big clue by writing the ratios of sides.
How do you find a missing length in a triangle? I have two triangles. The lengths given are 18:27:x and the other one is 14:21:28.

Perfect. I figured out what x was but I couldn't figure out how to show the calculations! The answer is 36, I think? Do you get the same thing?
Yes, absolutely!
Try this:
18 : 27 : x = 2*9 : 3*9 : x
14 : 21 : 28 = 2*7 : 3*7 : 4*7
Clearer now?

Yes, perfectly. Thank you. Sorry I wasn't clearer on my question asking
