Answer:

x = 4.2, LJ = 14.2

Step-by-step explanation:

When 2 chords of a circle intersect, then the product of the measures of the parts of one chord is equal to the product of the measures of the parts of the other chord, that is

10x = 6 × 7 = 42 ( divide both sides by 10 )

x = 4.2

Hence LJ = 10 + x = 10 + 4.2 = 14.2
