Answer:
621 / 629
Step-by-step explanation:
We are given the following information -
cos x = , and sin y =
Respectively we can use the following information -
sin( x + y ) = sin x ( cos y ) + sin y ( cos x ),
Knowing that cos^2x + sin^2x = 1, cos^2y + sin^2y = 1, we can calculate the value of sin x and cos y, plugging it into the first bit " sin( x + y ) = sin x ( cos y ) + sin y ( cos x ) "
Respectively cos y should be 35 / 37 -
Thus,
sin( x + y ) = ( 15 / 17 ) * ( 35 / 37 ) + ( 12 / 37 ) * ( 8 / 17 ),
sin( x + y ) = 621 / 629
