Explanation:

Step1: Use corresponding - angles property

Since \(m\parallel n\), the two given angles \((7x + 30)^{\circ}\) and \((8x+9)^{\circ}\) are corresponding angles and are equal. So we set up the equation \(7x + 30=8x + 9\).

Step2: Solve the equation for \(x\)

Subtract \(7x\) from both sides of the equation: \(30=x + 9\). Then subtract 9 from both sides: \(x=30 - 9\).

Answer:

\(x = 21\)
