Step-by-step explanation:
1. Set up your equation: 27/90 = y/100
2. Next you want to cross multiply: 2700 = 90y or 270 = 9y
3. Divide 270 by 9 to find your y: y = 30

For two secants that intersect at a point outside the circle, the product
(segment outside the circle)(whole secant) is the same for both secants!
What's the length of the entire secant that has <em>x</em>'s on it? 6x + 8x = 14x.
What's the length of the entire secant that has 9 and 7 on it? 9 + 7 = 16
