What are the coordinates used in the Path parameter of the Polyline class?

I'm drawing a bunch of carrier routes from the USPS API to an ArcGIS map. I need to only show the routes that are within a certain distance from a certain point. I have the latitude and longitude for the center point.

 

I thought the paths used by Polyline were made up of latitude and longitude sets multiplied by 100000, and I tried using them as such but that didn't work. The paths are generated from point sets that look like this:  -9214713, 3256075. When divided by 100000 they look like longitude and latitude, but I guess they're not.

 

What are these coordinates used in the Path parameter of the Polyline class, and how can I convert them to lat and lng for the purpose of calculating distance?
