I need help with my pre-calculus homework, please show me how to solve them step by step if possible. The image of the problem is attached. I got 6.245 for the other side of the triangle for reference if needed from the problem before this one.


EXPLANATION
We can affirm that the length of the adjacent leg is 5 units and the length of the hypotenuse is 8 units.
As given, the length of the third side is 6.245 units.
Now, computing sin A give us the following expression:
[tex]\sin A=\frac{6.245}{8}=\frac{1249}{1600}[/tex]The solution is 1249/1600
