In the figure, TU is tangent to the circle at point U. Use the figure to answer the questions.

Describe the relationship among the lengths of the segments formed by the secant, RT , and the tangent segment, TU . You may use words and/or an equation. (2 points)
Suppose RT=25 in. and ST=4 in. Is it possible to find the length of ? If so, show how to find the length. If not, explain why not. (3 points)

1. Power of point : TU^2 - ST^2 = RS*ST

2. 10

Step-by-step explanation:

1. By power of point,

RT * ST = TU^2

( RS + ST )  *  ST = TU^2

RS*ST + ST^2 = TU^2

TU^2 - ST^2 = RS*ST

2. TU^2 = 25*4 = 100

So, TU = 10

its 0.1 miles per minute

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula
