For this case we have:
By trigonometric property we have:
[tex]Sin\alpha=\frac{opposite leg}{hypotenuse}[/tex]
Where:
[tex]opposite leg = x[/tex]
[tex]hypotenuse = 8\\\alpha= 70 degrees[/tex]
Substituting:
[tex]Sin70 = \frac{x}{8}[/tex]
Clearing x we have:
[tex]x = 8 * sin70[/tex]
Thus, the equation is:[tex]x = 8 * sin70[/tex]
Answer:
[tex]x = 8 * sin70[/tex]
