The lines
and
touch a circle
of diameter 6 unit. If the centre of
lies in the first quadrant, find the equation of the circle
which is concentric with
and cuts of intercepts of length 8 on these lines.
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.

Centre of
lies over angle bisector of 
Equations of angle bisectors are

= ±
⇒ x = 5 or y = – 
Since centre lies in first quadrant so it should be on x = 5.
So let centre be (5, α ) ⇒ 3 =
⇒ α = 2, – 

From the figure r =
. But α ≠ –
so α = 2.
So equation of cirlce
is
.
