On the dimension toolbar there is the "angular" dimension icon. Check to see if you have the dimension tool bar turned on. If not go to the Dimension tab and scroll down to angular. The other way is to click on the line then hit the List icon. That will give you the properties of the line including length and angle. If you don't have the list icon turned on go to the modify tab, then scull down to properties.
This is the way it is in 2002LT and 2004LT
