Solve Block -These units are not compatible

Hi all,

 

I'm somewhat new to MathCad.

 

I'm trying to use a solve block to find a solution to several co-planar triangles that have some common sides/angles.  I've got it drawn up in CAD so I can check my calcs.   In the attached sheet, everything up to the solve block is verified. 

 

I ended up with ten variables and ten equations.  I entered all this in a solve block (very bottom of the sheet).  I'm getting a "These units are not compatible" error.  

 

It's possible my math is wrong or that some of my equations are redundant but before I dig into that, can anyone see any obvious error I made? Like in the syntax or units?

 

Thanks,

There was a unit mismatch in this equation (I now added the unit meter in the nominator)

Now the solve block works, but the results are non-real

So you may want to check your equations or your initial values.

Thanks!  that's what I was missing.  I'll dig deeper in my equations.
