length of perpendicular formula. Modulus sign is used since PQ is a length so it must be positive. DAmBnCsqrtA2B2 6-3-5710sqrt3625 -5506 5506 So the required distance is 5506 units correct to 3 decimal places.

Consider the equation of the line is ax by c 0 and coordinates are x 1 y 1 the slope should be ab. Coordinates and line equation is the prerequisite to finding out the perpendicular line. The length of perpendicular PQ is now simply left p_1 - p right left x_1cos alpha y_1sin alpha - p right.
Using Y 0 1 0 or Z 0 0 1 would give different perpendicular vectors.
10 10r9 - 4 -4r-1 - 11 -11r-13 0 which implies 237r -237 r -1. Then the line PM whose drs are 10r9 -4r-1 -11r -13 is perpendicular to the line L therefore we must have. With this in mind we can now manipulate the equation to determine the perpendicular line. - Ax1By1C A 2 B 2.
