Solution Steps

Step 1: Identify the Midsegment

In the given triangle KRL \triangle KRL , MS MS is a midsegment. By definition, a midsegment in a triangle is parallel to one side of the triangle and half its length.

Step 2: Set Up the Equation

Since MS MS is a midsegment, it is parallel to KR KR and half its length. Therefore, we can set up the equation: MS=12KR MS = \frac{1}{2} KR

Given: KR=2x KR = 2x MS=10+2x MS = -10 + 2x

Step 3: Solve the Equation

Substitute the given values into the equation: 10+2x=12(2x) -10 + 2x = \frac{1}{2} (2x)

Simplify the equation: 10+2x=x -10 + 2x = x

Subtract x x from both sides: 10+x=0 -10 + x = 0

Add 10 to both sides: x=10 x = 10

Final Answer

x=10 x = 10
