Answer:
y ≈ 4.3 cm
Step-by-step explanation:
Given 2 secants from an external point to the circle.
The the product of the external part and the entire part of one secant is equal to the product of the external part and the entire part of the other secant, that is
3(3 + y) = 2(2 + 6 + 3) = 2(11) = 22, that is
9 + 3y = 22 ( subtract 9 from both parts )
3y = 13 ( divide both sides by 3 )
y ≈ 4. 3 cm ( to the nearest tenth )
