Answer:
The angle of elevation is 31°.
Step-by-step explanation:
Remember that the sum of the interior angles of any triangle has to be 180°. Let's call our unknown angle x. We'll have that:
[tex]\begin{gathered} x+90+59=180 \\ \rightarrow x=180-90-59 \\ \\ \Rightarrow x=31 \end{gathered}[/tex]
This way, we can conclude that the angle of elevation is 31°.
