property: if a tangent and a secant intersect outside a circle, then the length of the tangent squared equals the length of the secant outside the circle times the length of the whole secant.

find the length of each segment. for any answers with a square root, write your answer in the form sqrt(__) with no spaces.

cf =
ce =
cb =

prove: ^2 = *
^2 = *

simplify both sides of the equation.
