Question

find ( mangle bfc ).

( mangle bfc=square^{circ} )

Explanation:

Step1: Identify vertical angles

Vertical angles are equal. $\angle BFC$ and $\angle EFD$ are vertical angles.

Step2: Calculate $m\angle BFC$

Since $\angle EFD = 28^{\circ}$, then $m\angle BFC=m\angle EFD = 28^{\circ}$

Answer:

$28$
