The elevation of hachure line A is option A: 100 feet
The most likely elevation of point X is 115 Feet
The most likely elevation of point B is 80 Feet
Hachure lines are short, closely spaced lines drawn downhill that indicate a depression or sunken area. They are drawn in the direction of the steepest slope, with shorter, thicker lines indicating steeper slopes and longer, thinner lines indicating gentler slopes.
The elevation of hachure line A is 100 feet because it is the first hachure line below the contour line labeled 125 feet. Contour lines are lines of equal elevation, so the elevation of all points on a contour line is the same.
