Question

A={1,3}, B={1,2,3} and C={4,2,1} then prove that A² = B² intersection C²​

Answer 1

Answer:

Correct option is

C

(4,5,6)

Let the point C be (i,j,k).

Since, B divides AC in the ratio 1:2

Coordinates of B should be (

3

2+i

,

3

4+j

,

3

k+6

)

Comparing the values given already for B, we get,

i=4, j=5 and k=6
