Question

9.) find x so l || m. (2x - 4)°

Explanation:

Step1: Use perpendicular - angle property

Since \(l\parallel m\) and the perpendicular line forms a \(90^{\circ}\) angle, we set up the equation \(2x - 4=90\).

Step2: Solve for \(x\)

Add 4 to both sides of the equation: \(2x=90 + 4\), so \(2x=94\). Then divide both sides by 2: \(x=\frac{94}{2}\).

Answer:

\(x = 47\)
