Given:AB = 7 BC = 9 AD = 9 Find:AE

Question

Consider the following theorem.

If two secant segments are drawn to a circle from an external point, then the products of the length of each secant with the length of its external segment are equal.

Use the figure to answer the question.

1. 
   

Given:AB = 7

BC = 9

AD = 9

Find:AE

Answer 1

The theorem basically says that AC * AB = AE * AD.

So solve for AE using the information provided

Answer 2

(AB)(BC) = (AD)(DE)

Can you substitute values and answer?
