Question

7.) find x so l || m. 124° (3x + 40)° x = ____

Explanation:

Step1: Use corresponding - angles property

If \(l\parallel m\), then the corresponding angles are equal. So, \(3x + 40=124\).

Step2: Solve the equation for \(x\)

Subtract 40 from both sides: \(3x=124 - 40\), so \(3x = 84\). Then divide both sides by 3: \(x=\frac{84}{3}\).

Answer:

\(x = 28\)
