I am trying to find the angle from the equation pasted below. In Matlab, I got the angle and it is about 104 degrees but I cant solve it in Mathcad. I have attached the Mathcad 9 sheet.

If you really mean MatLab then you are in the wrong forum 🙂
To make - what you show in the picture - an equation, you would have to provide a value for Im(A) first.
Furthermore you would have to define R.E. You defined R.E21, L.1 and L.2 but never used those variables.
Additionally you sure should add the proper units - after all you are using Mathcad and not MatLab 😉
You may consider your excessive usage of symbolic evaluations - they are not necessary to most part.
And if you use solve block with "find" or the root() function (see attached file) you can avoid symbolic calculations altogether.
Here is attached a possible approach where I assumed R.E = R.E2 and Im(A)=175 Ohm (so that we get near the 104°).
Using symbolics to develop formulas is good practice. Solving for values is more a numeric practice, and Mathcad was always a numeric program.

Usually, impedance of electric circuit has an angle from -90 to 90 degree. Assuming Im(Z1)=175.
