find the measure of x.

Explanation:

Step1: Use the property of corresponding angles

Since the two lines are parallel, the angle \(120^{\circ}\) and \(15(x + 2)\) are corresponding angles. So \(15(x+2)=120\).

Step2: Solve the equation

Divide both sides of the equation \(15(x + 2)=120\) by \(15\):
\(x+2=\frac{120}{15}\)
\(x + 2=8\)
Subtract \(2\) from both sides:
\(x=8 - 2\)

Answer:

\(x = 6\), so the answer is B.
