Help with this trig problem with unknown height

I tried using this formula and I'm having difficulties finding the variables. I'm not sure if my algebra is wrong or if I'm using the wrong formula for the equation

Please quote the problem exactly as given to you.

I suspect you have left out some information, perhaps about angles (e.g. are the two slanted lines at the same slope?).
 
I did not have the angles. I tried a different approach and will post it. The only knowns I have are one length is 58, another is 73, and the distance between them is 49.8 however I need to find the height of y

You missed my point. With only the three lengths, there is not enough information! There are many possible values for y. Here are two examples:

So, what is the actual problem? What additional information can you use to narrow it down?
 
Thank you very much for the clarification! I understand which information is missing and I have an idea where to look for it. It was a practical problem for a design. I appreciate your help!

I did also make a suggestion of an addition, based on what your drawing looks like: "(e.g. are the two slanted lines at the same slope?)" . That would be a natural requirement, and would make the problem solvable:

If that's not appropriate, and you can't find a good constraint, you could show us the context so we could help with that.
