A Delta is formed by the lines whose combined equation is given by `(x+y-9)(xy-2y-x+2)=0`
if the circumcentre of Delta is `(h,k)` then value of `|h-k|` is

Text Solution

Verified by Experts

The correct Answer is:
1
The sides are `x+y-9=0` and `y=1`
`because` circumcentre is `(5,4)`
`because|h-k|=1`
