Still don't get it though Math student
I find it hard ... But I think I will get there. ... Slowly but surely ... Math student
I still dont understand To solve this verbal math problem are needed these knowledge from mathematics:

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. Two vectors given by its magnitudes and by included angle can be added by our vector sum calculator. See also our trigonometric triangle calculator. Pythagorean theorem is the base for the right triangle calculator.
