Answer:
66.8°
Explanation:
We can represent the situation with the following figure
So, we can calculate the measure of angle θ as follows
[tex]\begin{gathered} \tan\theta=\frac{\text{ Opposite side}}{\text{ Adjacent side}} \\ \\ \tan\theta=\frac{49}{21} \\ \\ \tan\theta=2.33 \\ \theta=\tan^{-1}(2.33) \\ \theta=66.8 \end{gathered}[/tex]Therefore, the elevation of the sun is 66.8°
