-429/629
Step-by-step explanation:
Use angle difference formula:
sin (x - y) = sin x cos y - sin y cos x
Assuming x and y are in the first quadrant:
sin (x - y) = sin x cos y - √ (1 - cos²y) √ (1 - sin²x)
Plugging in values:
sin (x - y) = (8/17) (12/37) - √ (1 - (12/37) ²) √ (1 - (8/17) ²)
sin (x - y) = (8/17) (12/37) - (35/37) (15/17)
sin (x - y) = - 429/629
