Answer:
The correct answer is option A. 6
Step-by-step explanation:
It is given that, QR is the median of trapezoid MNOP
To find the value of x
From the given information we can write,
MP + ON = 2(QR)
9x - 42 + 30 = 2(x + 15)
9x - 42 + 30 = 2x + 30
9x - 2x = 42
7x = 42
x = 42/7 =6
Theerfore the correct answer is option A. 6
