Here is another method to make the same without using any angles :-)
Inspired from the model How to model a Dodecahedron from scratch by Steen Winther.
Here is the model:
Request: Dodechahedron
Hope this will be helpful to many..

1. Step 1:

   First, make a simple pentagon and make a planer surface from it.
   

   

2. Step 2:

   Save the file with any name, Say "Surface".
   

   

3. Step 3:

   Now Make an Assembly and import that part "surface".
   

   

4. Step 4:

   Insert another same surface and make co-incident relations(mates) of
   1. edge-to-edge
   2. Point-to-Point.
   As shown in the picture.
   

   

5. Step 5:

   Insert 3rd surface and again make relations(mates) like the previous one.
   but with another edge of the base surface as shown in the picture.
   

   

6. Step 6:

   Now make an edge-to-edge mate with one edge of the second part and second edge of the third part as shown in the pictures.
   

   

7. Step 7:

   Add another part and make two edge-to-edge mates as shown in the picture.
   

   

8. Step 8:

   Then insert more surfaces and add all the required mates,
   i have shown the last mate required in the assembly.
   

   

9. Step 9:

   Click "Save as".
   

   

10. Step 10:

    Select "Part" as type to save the file with any name say "Final".

    

11. Step 11:

    Remember to check "exterior Faces" in "Geometry to save".
    

    

12. Step 12:

    Now open the saved part file and knit all the surfaces to make the part a solid.
    Remember to Check "Try to make solid" under selections.
    

    

13. Step 13:

    Additionally we can add fillets to the model.
    Best way to add fillets is to use FilletExpert.
    

    

14. Step 14:

    Here is a cascade view of all the files.(Surface, Assembly and Final).
