Answer:
0.4706
Step-by-step explanation:
Using trigonometric formulas we know:
[tex]sin(x) = \frac{opposite}{hypotenuse}[/tex]
Here, our opposite is the side opposite to the angle A, which in this case is the line BC which is equal to 8.
The hypotenuse is the diagonal line, which in this case is AB, and this is equal to 17.
Therefore,
[tex]sinA = \frac{8}{17} =0.4706[/tex]
Our final answer is 0.4706.
