Question

1. one way to get started is with a vertical angle relationship. what is $m\angle afb$? $m\angle afb=28$ 5) how are $\angle afb$ and $\angle bfc$ related? $\angle afb$ and $\angle bfc$ combine to form a straight angle. $\angle afb$ and $\angle bfc$ are vertical angles. $\angle afb$ and $\angle bfc$ combine to form a right angle.

Explanation:

Step1: Recall the definition of a right angle

A right angle measures \(90^{\circ}\).

Step2: Analyze the relationship between \(\angle AFB\) and \(\angle BFC\)

From the figure, \(\angle AFB = 28^{\circ}\). If we consider the sum of \(\angle AFB\) and \(\angle BFC\), since \(AF\perp GC\) (right - angle symbol at \(F\) between \(AF\) and \(GC\)), the sum of \(\angle AFB\) and \(\angle BFC\) is \(90^{\circ}\). That is, \(\angle AFB+\angle BFC = 90^{\circ}\).

Answer:

\(\angle AFB\) and \(\angle BFC\) combine to form a right angle.
