Question

Question is stated in picture. The figure is a triangular piece of cloth

Answer 1

Alternative D - 8 sin(35°)

Step-by-step explanation:

Sin(x) is defined as:

`\begin{gathered} \sin (x)=\frac{\text{Opposite side}}{Hypotenuse\text{ }} \\ \end{gathered}`

In this exercise,

BC is the opposite side to 35°

AC is the hypotenuse and measures 8 in

Then:

`\begin{gathered} \sin (35\degree)=(BC)/(8) \\ \sin (35\degree)\cdot8=BC \\ BC=8\sin (35\degree) \end{gathered}`
