Solution:
To figure out the value of a, we will use the trigonometric ratio below
[tex]\begin{gathered} sin\theta=\frac{a}{c} \\ \theta=41^0 \\ c=25m \\ sin\theta=\frac{opposite}{hypotenus} \\ S=\frac{O}{H} \end{gathered}[/tex]
By substituting the values, we will have
[tex]\begin{gathered} s\imaginaryI n\theta=\frac{a}{c} \\ \sin41=\frac{a}{25m} \\ a=25\times sin41 \\ a=16.4 \\ a\approx16cm \end{gathered}[/tex]
Hence,
The value of a to the nearest whole number is
[tex]a=16m[/tex]
