1) The best way to tackle this question is by sketching out what's been given to us.
2) Note that the angle of elevation is found by the tangent. So let's apply this trig ratio:
[tex]\begin{gathered} \tan(67)=\frac{29}{x} \\ \tan(67)x=29 \\ x=\frac{29}{\tan(67)} \\ x=12.30976\approx12.3ft \end{gathered}[/tex]Hence, the ladder is 12.3 ft away from the base of the building
