Answer:

Option D, I agree with neither Elena nor Lin

Step-by-step explanation:

The remaining part of the question is attached herewith

Solution

As we can see in the image

ED is perpendicular to AB and BC is perpendicular to AB

Thus, as per the Pythagoras theorem,

AC^2 = AB^2 + BC^2

14^2 = 6^2 + BC^2

BC^2 = 196-36 = 160

BC = 12.649 OR 12.65

Hence, option D

I agree with neither Elena nor Lin
