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 is 141.79 m
The answer in spanish

Ok, so you automatically know that you are subtracting 6 from 10 to get 4. So, in order to figure out how it is 1/3 of that number, it is going to be multiplied by 3, getting 18. So, the number would be 18.
