How to calculate Perpendicular distance between a point and a line The perpendicular distance (d) of a line Ax + By+ C = 0 from a point (x1 ,y1) is given by d = | Ax1 + by1 + c|/ root (A^2 + B^2) complete explanation of formula and solved example. 1  Education. 2  Standard YouTube License.

You can calculate the height of an object using the distance and angle. distance * cos(angle), where distance is the horizontal distance to the object, and angle is the angle above horizontal of the top of the object (from the viewer).The result will be the height above the viewer.p vote 1 down vote.
