The what prevents food or liquids from getting into the lungs?

1 answer:

6 0

I think the correct answer from the choices listed above is option A. The pharynx is what prevents food or liquids from getting into the lungs. The pharynx is the throat where food pass. There is a flap of cartilage that covers the windpipe (trachea) when swallowing occurs, preventing food and liquids from entering the trachea.

This falls under geometry. The two labeled angles are congruent, which means the line segment between them (AD in the image) is a bisector of the angle at vertex A. Use the angle bisector theorem, which says that

$\dfrac{BD}{DC}=\dfrac{AB}{AC}\iff\dfrac{12}{(5+9x)-12}=\dfrac{15}{25}$
