Answer:
39°
Step-by-step explanation:
==>Given:
Shadow length = 20ft
Flag height = 16ft
==>Required:
Angle of elevation of sun (θ)
==>Solution:
To calculate the angle of elevation of the sun, recall the trigonometry formula SOHCAHTOA.
We are given adjacent side = 20ft, and opposite side = 16ft
Therefore, we would use TOA, which is:
tan θ = Opposite/Adjacent
tan θ = 16/20
tan θ = 0.8
θ = 38.6598083 ≈ 39°
Angle of elevation of the sun = 39°
