You can also this manually by identifying the height at the top and bottom of the slope from a map showing the contours (e.g. 25K Raster or VML) and measuring the horizontal distance between these points and then calculate the slope angle. 
You can also download the DTM data and use a GIS or CAD program such as ArcGIS, QGIS or AutoCAD to do the calculation of the slope angle.
