Answer:
EB = 20
Explanation:
Given 2 chords intersecting inside a circle, then
Th product of the parts of one chord is equal to the product of the parts of the other chord, that is
10x = 8(x + 5) ← distribute
10x = 8x + 40 ( subtract 8x from both sides )
2x = 40 ( divide both sides by 2 ), thus
x = EB = 20
