Question

one way to get started is with a vertical - angle relationship. what is m∠afb? m∠afb = 28°. how are ∠afb and ∠bfc related? ∠afb and ∠bfc combine to form a right angle. what is m∠bfc? m∠bfc =

Explanation:

Step1: Identify angle - relationship

We know that $\angle AFB$ and $\angle BFC$ combine to form a right - angle. A right - angle measures $90^{\circ}$.

Step2: Set up equation

Let $m\angle AFB = 28^{\circ}$ and $m\angle BFC=x$. Then $m\angle AFB + m\angle BFC=90^{\circ}$, so $28^{\circ}+x = 90^{\circ}$.

Step3: Solve for $x$

Subtract $28^{\circ}$ from both sides of the equation: $x=90^{\circ}- 28^{\circ}$.
$x = 62^{\circ}$

Answer:

$62$
