Answer: B
Explanation:
Given that DE is the mid point. Since DE is the midpoint, it will be equal to the half value of BC. That is,
DE = 1/2 × BC
Where
DE = 3x - 5
BC = 26
Substitute the values into the equation
3x - 5 = 1/2 × 26
3x - 5 = 13
Collect the like terms
3x = 13 + 5
3x = 18
x = 18/3
X = 6
The correct option is B
