2. For the diagram below, which of the following represents the length of MN to the nearest tenth? (1) 15.4 (3) 26.3 24 (4) 28.6 (2) 20.1 40° M N

By Trigonometric Ratio,
[tex]\begin{gathered} \tan 40=\frac{24}{MN} \\ \text{Crosss multiplying we get,} \\ MN=\frac{24}{\tan 40}=28.60\approx28.6 \end{gathered}[/tex]The solution is, MN = 28.6 ( option 4 )
