Question Analysis

This question focuses on the Side - Splitter Theorem. The main task is to use the proportional relationship created by a line parallel to one side of a triangle (  ) to find the unknown side length .

 

Key Concept Explanation

The Side - Splitter Theorem states that if a line is parallel to one side of a triangle and intersects the other two sides, it divides those sides proportionally. In , since , we have .

 

Step - by - Step Solution

1. First, identify the known side lengths: , , and .

2. According to the Side - Splitter Theorem
