Question Analysis

This question focuses on using the property of a median in a triangle to find the length of a segment. The key is to understand that a median bisects the opposite side, allowing us to set up an equation to find the value of  first, and then determine the length of .

 

Key Concept Explanation

A median of a triangle is a line segment that joins a vertex to the mid - point of the opposite side. In , since  is a median,  is the mid - point of , which means .

 

Step - by - Step Solution

1. Since  is a median of , we know that .

2. We are given that  and .

3. Set up the equation based on the median property: .

4. Solve the equation for
