Question

find the ratio in which level 5 divide the line segment joining the point 15, 5 and 9, 20​

Answer 1

Answer:

Step-by-step explanation:

Hi !

We have to apply section formula to find the answer .

Let the point P(11,15) divide the line segment AB in the ratio m₁:m₂

A = (15,5) ==> x₁ = 15 , y₁ = 5

A = (9,20)  ==> x₂ = 9 , y₂ = 20

P = (11,15) ==> x = 11 , y = 15

Here is the formula :-

x =m2x1 +m1x2/m1+m2 

11 = m1y2+m2y1/m1+m2

11(m₁ + m₂) = 9m₁ + 15m₂

11m₁ + 11m₂ =  9m₁ + 15m₂

2m₁ = 4m₂

m₁/m₂ = 4/2

m₁/m₂ = 2/1

The ratio is 2:1
