Question

find ( mangle bfc ).
( mangle bfc=)
an error has occurred. please enter a number.

Explanation:

Step1: Use vertical angles property

Vertical angles are equal. $\angle BFC$ and the angle composed of a right - angle ($90^{\circ}$) and $28^{\circ}$ are vertical angles.

Step2: Calculate the measure of $\angle BFC$

$$m\angle BFC=90^{\circ}- 28^{\circ}$$

$$m\angle BFC = 62^{\circ}$$

Answer:

\(62\)
