Question

A (15 , 5), B (9 , 20) an A-P-B . Find the ratio in which P (11 , 15) divides segment AB.
​

Answer 1

Answer:

Step-by-step explanation:

A(15,12) = (x1,y1)

B(9,20) = (x2,y2)

and P(11,15) = (x, y)

m:n=?

Section formula,

X = mx2+nx1/ m+n

11 = m(9) + n(15)

11(m+n) = 9m+15n

11m + 11n = 9m+15n

11m-9m = 15n-11n

2m = 4n

m/n = 4/2

m/n= 2/1

So, Answer is m:n = 2:1
