You can use the function al_nlegsolve with any initial
assumptions (because the equations are linear)

By default, trig are in decimal radian in all CAS.
Recast your solutions, fill-in the unit place holder.

Hi Martin. I use Maxima's ev() because SMath's Assign() only works with the variable names, instead others, like xo, yo, and SMath's at() doesn't works for the symbolic evaluation, as shown this picture:

This is a workaround for use only SMath native functions or plugins, without any explicit Maxima function:

Best regards.
