Answer:
Step-by-step explanation:
Using the section formula, if a point (x,y) divides the line joining the points (x
1
,y
) and (x
2
) in the ratio m:n, then
(x,y)=(
m+n
mx
+nx
,
my
+ny
)
The vertices of the triangle are given to be (x
),(x
3
). Let these vertices be A,B and C respectively.
Then the coordinates of the point P that divides AB in l:k will be
(
l+k
lx
+kx
ly
+ky
The coordinates of point which divides PC in m:k+l will be
⎩

⇒(

+my
if 3y + 5 = 47
then
y=14
4/10 is equivalent to 2/5
because 4/10 is written as 0.4 in decimal form and so is 2/5, which means they are equivalent
where is the question????
