Answer:
y ≈ 4.3 cm
Step-by-step explanation:
Two secants drawn from outside the circle, then
The product of the external part and the entire secant is equal to the product of the external part and the entire secant of the other secant, that is
3(3 + y) = 2(2 + 6 + 3) ← distribute both sides
9 + 3y = 2 × 11
9 + 3y = 22 ( subtract 9 from both sides )
3y = 13 ( divide booth sides by 3 )
y = 13 ÷ 3 ≈ 4.3 ( to the nearest tenth )
(X-6)²+(y+7)²=121 , flip the signs of the coordinates and the last number is the radius squared
