The question in English is
<span>A person of 1.75m tall observes a plane as shown in the figure, at what approximate height with respect to the ground is the plane
</span>
see the picture attached with letters to better understand the problem
we know that
tan 35°=BC/AC---------> BC=AC*tan 35°----> BC=200*tan 35°--> BC=140.04 m
approximate height of the plane=140.04+1.75=141.79 m
the answer is141.79 mThe answer in spanish

Sabemos que
tan 35°=BC/AC----> BC=AC*tan 35°----> BC=200*tan 35°--> BC=140.04 m
altura aproximada del avion=140.04+1.75=141.79 m
La respuesta es141.79 m
