Answer 1

Given - two tangent lines are drawn from the point B

To find - the value of BC

Explanation - when tangent lines are drawn for outside of the circle then the length of line formed is equal

We get

AB=BC

`x+3 =3x-1\\x-3x=-1-3\\-2x=-4\\x=2`

BC=
`3x-1 =3(2)-1=6-1=5`

The length of BC = 5

Final answer - The option A is correct, the length is 5
