For Review Exercises 21 to 23, D E ¯ | | A C ¯ A D = 2 , A B = 10 , B E = 5 , A C = ?

To determine

To find:

The value of BC.

Explanation

Given:

DE¯||AC¯

Calculation:

First to show, ΔDBE similar to ΔABC.

Since, corresponding angles are equal, then

BDE=BAC(DE¯||AC¯)

BED=BCA(DE¯||AC¯)

Here, ΔDBE similar to ΔABC

Let EC=x
