Help with sketch that can't be solved.

Hello there.
I'm pretty new to onshape and I'm having a hard time understanding why the sketch I'm working on can't be solved.
It's Sketch 2 in the following document: https://cad.onshape.com/documents/50551f47e04ca775495f4553/w/bd04381752b160983ac1fbce/e/026aefda3d37cc5c6dcd89fc?renderMode=0&uiState=67f1374dde578c2ccffd702a
The issue appears when creating the smaller circles of 5mm diameter, on the "tips" of the bigger inscribed hexagon.
When I try to make the 6 circles equal (by selecting all of them and pressing the equal button), I get the "can't resolve" error, and I'm really not sure why.
Any help is appreciated.
Thank you!

Hello Riccardo. One area that didn't look right to me is shown in the image below (I turned on Show Constraints first). Elimination of the Intersect constraint that is circled in the image below allowed the sketch to so solved. I'm not sure but I think that constraint made the sketch over defined.
If you look at Part Studio 2, the Circumscribed Polygon tool was used in lieu of the Circular Pattern tool. As for the small circles, I created one and made it tangent to the two adjacent lines at the desired position. I then used the Circular Pattern tool to create the rest. I expected the circles to all go black at the time of creating the pattern, but they didn't until I forced another circle tangent to the two lines at it's position. - Scotty
