Answer:
Step-by-step explanation:
The relevant relation is that the product of distances from the point of intersection of secants to the two points of intersection of each with the circle is a constant. The point of tangency counts as both points of intersection.
__
By way of example, the product of distances to the circle for the tangent segment is 10·10 = 100
This is also the product of the distances on the secant that intersects the tangent:
100 = 5(5+x+9)
20 = x +14 . . . . . divide by 5
x = 6 . . . . . . . . . . subtract 14
__
The same is true when the secants intersect <em>inside</em> the circle:
6·9 = y·3
y = 18 . . . . . . divide by 3
Write what you know in an equation: 27=30%•X. Divide 27 by .30 to get X alone: 27/.30=90. 27 is 30% of 90 :)
Answer:
-1/15 because it is closer to zero on the negative half of a number line.
