Answer:
to the nearest degree = 77°
Explanation:
This is a question under trigonometry
from the question we can find that The building is 210 feet tall and the length of its shadow is 50 feet.
The relationship between opposite and adjacent of the triangle is tan
Therefore tanθ = 
θ = tan⁻¹ 0.2380
= 13.39°
then we have to calculate the measure of the angle between the end of the shadow and the vertical side of the building , which is equal to
90 - 13.39=
=76.61°
to the nearest degree = 77°

3) <u>the insides of the pyramids:</u> The pyramids were usually painted, and had treasures inside of them (where the pharoah was buried). This showed their richness and might, and how much they believed that their pharoah was a god, or god-send. The pictures on the wall also showed how educated most of them were, in that they can produce reliefs and artworks describing the kings life.
