Unitary Method

The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.

### Geometry Problem

**Question:**

8) In the diagram below of circle O, chord DF bisects chord BC at E. If $ BC = 12 $ and $ FE $ is $ 5 $ more than $ DE $, then $ FE $ is:
1) $ 13 $
2) $ 9 $
3) $ 6 $
4) $ 4 $

**Diagram Explanation:**

The diagram depicts a circle with center $ O $. Within the circle:
- Chord $ DF $ bisects chord $ BC $ at point $ E $.
- Chord $ BC $ is labeled with points $ B $ and $ C $ on the circumference of the circle.
- Point $ E $ is the midpoint of chord $ BC $, and thus, $ BE = EC = \frac{BC}{2} = \frac{12}{2} = 6 $.
- The lengths $ DE $ and $ FE $ are part of chord $ DF $, with point $ E $ lying somewhere along the length of $ DF $.

To find $ FE $:
- Note that $ FE $ is $ 5 $ more than $ DE $.
- Let $ DE = x $.
- Therefore, $ FE = x + 5 $.
- Using the properties of the circle and the Pythagorean Theorem in triangles:

Given (from diagram geometry):
- $ BE = 6 $
- $ EC = 6 $

Note: $ E $ is the midpoint, so $ BE = EC = 6 $.

**Calculation:**

Since $ DF $ bisects $ BC $ perpendicularly at $ E $ (or using geometric properties), we have:
- Triangle $ DEF $ gives $ DE^2 + BE^2 = FE^2 $.

By setting up the equations:
- $ x^2 + 6^2 = (x + 5)^2 $
- Simplifying this will help find the value of $ FE $.

This setup allows us to determine the correct answer among the provided multiple-choice options.

**Answer:**
2) $ 9 $
