Answer:
=63.9°
Step-by-step explanation:
To find the angle of elevation using the shadow of an object, we use the trigonometric ratio Tangent.
Tan∅=opposite/adjacent
Opposite is the height of pole while adjacent is the shadow of the pole.
The tan of the angle of elevation= height of the pole/length of shadow
Tan ∅=45/22
∅= Tan⁻¹(45/22)
=63.9°
Angle of elevation=63.9°
