Question

if a || b and e || f, what is the value of y? 87 88 91 92

Explanation:

Step1: Use the property of parallel lines

Since \(a\parallel b\) and \(e\parallel f\), \((x + 1)^{\circ}+(x - 3)^{\circ}=180^{\circ}\) (consecutive interior angles).

Step2: Find the value of \(y\)

Since \(a\parallel b\), \(y^{\circ}=(x + 1)^{\circ}\) (corresponding angles). Substitute \(x = 91\) into \(x + 1\), we get \(y=x + 1=91+1 = 92\)

Answer:

92
