Step-by-step explanation:
Since the chord is a tangent to the smaller circle, it will meet the radius of the smaller circle at right angle.
Let
be the length of half of the chord. See diagram in attachment.
Then from Pythagoras Theorem,




We take the positive square root of both sides to obtain,

The length of the chord is

The correct answer is A
6=4x+2y
x= y intercept you just have to know the pieces of the equation almost like a puzzle. its written backwards is all
