Question

what is ( mangle dfc )? ( 45^{circ} ) ( 80^{circ} ) ( 125^{circ} ) ( 135^{circ} )

Explanation:

Step1: Use the property of vertical angles

Vertical angles are equal. \(\angle AFE\) and \(\angle DFC\) are vertical angles.

Step2: Determine the measure of \(\angle DFC\)

Since \(\angle AFE = 125^{\circ}\), then \(m\angle DFC=125^{\circ}\) (by the vertical - angles theorem).

Answer:

C. \(125^{\circ}\)
