How to measure the angle of a line?

OK, so I drew a line in X7. I'd like to be able to see its angle and length. I can get its horizontal and vertical size and do the math, but it seems I should just be able to see it displayed. I can get the length displayed in the object properties under curve properties, but no angle.

It seems silly to use the angle dimension tool, which draws an angle dimension rather than just showing you the angle of the line.
