#### To solve this example are needed these knowledge from mathematics:

Try conversion angle units angle degrees, minutes, seconds, radians, grads. For Basic calculations in analytic geometry is helpful line slope calculator. From coordinates of two points in the plane it calculate slope, normal and parametric line equation(s), slope, directional angle, direction vector, the length of segment, intersections the coordinate axes etc.
