Contour farming involves ploughing, planting and weeding along the contour, i.e, across the slope rather than up and down. Contour lines are lines that run across a (hill) slope such that the line stays at the same height and does not run uphill or downhill.
Each interior angle of a regular polygon is 45° more than its exterior angle, then find its number of sides.
