Question

Find the ratio in which 3 by 4 5 by 12 / line segment joining the point a 1 by 2 3 by 2 and 2 by minus 5

Answer 1

Let the ratio be k:1

By section formula,

(2k+1/2/k+1, -5k+3/2)=(3/4,5/12)

2k+1/2/k+1=3/4     (Taking one of them)

By cross multiplication,

8k+4/2=3k+3

8k+2=3k+3

8k-3k=3-2

5k=1

K=1/5

Therefore the ratio is 1:5

I hope it helps you
