2.8 easy just think about it
See the picture in the attached figure to better understand the problem
we know that
in the right triangle ABC
tan 80°=opposite side angle 80°/adjacent side angle 80°
tan 80°=BC/AC----->BC=AC*tan 80°-----> BC=75*tan 80°---> BC=425.35 m
the approximate height of the building=BC+<span>eye level
</span>the approximate height of the building=425.35+1.5----> 426.85 m
the answer isthe approximate height of the building is 426.85 m
