The equations of the tangents to the circle` x^2+y^2 =13` the point whose abscissa is 2, are

A

`2x+3y=13,2x-3y=13`

B

`3x+2y=13,2x-3y=13`

C

`2x+3y=13,3x-2y=13`

D

None of the above

Text Solution

Verified by Experts

The correct Answer is:
A
Let the point be `(2,y_(1))` then
`2^(2)+y_(1)^(2)=13`
`rArr y_(1)=+-3`
Henc,e the required tanget are `2x+-3y=13`
