Find the coordinates of the foot of the perpendicular from(6,8)
to the line through (1,5) and (9,3)

Step-by-step explanation:

Find the coordinates of the foot of perpendicular drawn from

the point A (1, 8, 4) to the line joining the points B(0, -1, 3) and

C(2, -3, -1)

Apart from this, there is another answer

Write this second answer either.

If you want to find the coordinates of foot of perpendicular... The process is quite simple. If you are give an equation of line and point which is perpendicular to that line, find their slopes first, by the formula m1.m2=-1 . Then, when you have both the slopes, make an equation of line similar to the line which is given ..using one- point form [Y- Y1= m(x- x1)]. Now u have two lines, using these two lines, by elimination method u can find the two points ( co ordinates) of foot of perpendicular.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
