Answer:
12.6 feet
Step-by-step explanation:
we know that
The formula of slope is "rise over run", where the "rise" (means change in y, up or down) and the "run" (means change in x, left or right)
The slope is also the tangent of the angle of the opposite side (rise) divided by the adjacent side (run)
In this problem
we have
[tex]m=tan(6^o)[/tex]
[tex]run=120\ ft[/tex]
[tex]rise=?[/tex]
substitute
[tex]tan(6^o)=\frac{rise}{120}[/tex]
[tex]rise=tan(6^o)(120)=12.6\ ft[/tex]
