Question

if y || z, find the value of x.

Explanation:

Step1: Set up equation

Since \(y\parallel z\), the corresponding - angles are equal. So we have \(3x + 6=90\) (assuming the angle marked \(90^{\circ}\) and \(3x + 6\) are corresponding or alternate - interior/exterior angles based on parallel lines properties).

Step2: Solve for \(x\)

Subtract 6 from both sides of the equation: \(3x=90 - 6\), so \(3x = 84\). Then divide both sides by 3: \(x=\frac{84}{3}\).

Answer:

\(x = 28\)
