Using the slope concept, considering it's value of 0.3415, it is found that the angle of elevation is of 18.86º.
The slope is given by the vertical change divided by the horizontal change, and it's also the tangent of the angle of depression.
Hence, we have that:
[tex]\tan{\alpha} = 0.3415[/tex]
[tex]\alpha = \arctan{0.3415} = 18.86^\circ[/tex]
