Question is attached, Don't worry explaining too much just make sure the answer is correct :))

Answer:
The image below will explain the question
To figure out the length of portion BC, we will use the trigonometric ratio below
[tex]\begin{gathered} \sin\theta=\frac{opposite}{hypotenus} \\ oppsite=BC \\ hypotenus=8in \\ \theta=35 \end{gathered}[/tex]By substituting the values, we will have
[tex]\begin{gathered} \sin(\theta)=\frac{oppos\imaginaryI te}{hypotenus} \\ \sin35=\frac{BC}{8} \\ cross\text{ multiply, we will have} \\ BC=8\sin35 \end{gathered}[/tex]Hence,
The final answer is
[tex]\Rightarrow8\sin35^0[/tex]The FOURTH OPTION is the right answer
