Answer:
[tex]45\degree[/tex]
Step-by-step explanation:
We use trigonometry to find the angle of elevation.
From the diagram, the angle of elevation of the sun is [tex]\angle A[/tex]
Recall the mnemonics SOH CAH TOA.
[tex]\tan A=\frac{Opposite}{Adjacent}[/tex]
[tex]\tan A=\frac{5}{5}[/tex]
[tex]\tan A=1[/tex]
[tex]A=\tan^-1{1}=45\degree[/tex]
Therefore the angle of elevation of the sun is [tex]45\degree[/tex]
