3.3.19 Line and plane in space
condition: Find the projection of the point \( M(3,4,-5) \) onto the line \[ \frac{x-5}{2}=\frac{y-3}{1}=\frac{8-z}{4} \]
Straight lines and planes in space. Intersection of lines and planes, calculation of the distance of a line and a plane, angles between lines and planes, finding equations of lines and planes in space, and much more.
