Question

letters a, b, c, and d are angle measures. which should equal 105° to prove that f || g? a b c d

Explanation:

Step1: Use the property of supplementary angles

When two lines are parallel, consecutive interior angles are supplementary. If \(f\parallel g\), then the angle \(d\) and the \(75^{\circ}\) angle are consecutive interior angles. So \(d + 75^{\circ}=180^{\circ}\).

Step2: Solve for \(d\)
