Question

Determine the value of X

AB is the mid segment of triangle LMN. Determine the value of X

Answer 1

B. 4

Explanation:

Since ,AB is the mid segment of triangle LMN

Then

`\Longleftrightarrow AB=(MN)/(2)`

`\Longleftrightarrow x+8=(5x+4)/(2)`

`\Longleftrightarrow 2*(x+8)=5x+4`

`\Longleftrightarrow 2x+16=5x+4`

`\Longleftrightarrow 16-4=5x-2x`

`\Longleftrightarrow 3x=12`

`\Longleftrightarrow x=(12)/(3)=4`
