i dont really get it

a)  This is known as  the  Tangent-Secant Theorem....it says that :


"When a tangent and a secant are drawn from one single external point to a circle, the square of the length of tangent segment must be equal to the product of lengths of whole secant segment and the exterior portion of secant segment."


In plain English....it says that    TU^2  = TR* TS


b)  RT  =  9      ST  =  4


We can find  TU  thusly :


TU^2  = TR * TS


TU^2  = RT * ST


TU^2  =  (9) * (4)


TU^2   =  36       take the square root of both sides


TU  =   6




cool cool cool
