Answer:
27°
Step-by-step explanation:
You want to know the angle of elevation of the top of a 58 m building seen from a spot 2 m above the ground and 110 m away.
Tangent
The tangent of an angle relates the horizontal and vertical distances:
Tan = Opposite/Adjacent
Here, the side adjacent to the angle of elevation is 100 m, and the side opposite is the height of the building above eye level, 58 m - 2m = 56 m.
The angle is ...
tan(α) = (56 m)/(110 m)
α = arctan(56/110) ≈ 27°
The angle of elevation is about 27°.
