Question

in the following figure a blinear pair c d x ratio Y ratio Z is equal to 4 ratio 5 ratio 6 then find X Y and Z​

Answer 1

Answer:

Let P(x,3) divide the line segment joining the points A(−4,2) and B(3,6) in the ratio k:1

∴ Coordinates of P is (

But coordinate of P is (x,3)

⇒

6k+2

=3

6k+2=3k+3

3k=1⇒k=

∴ The required ratio is

:1 i.e., 1:3 (internally)

∴ Coordinate of P is (
