Hi miss Ng, can you tell me the answer for the questions below:

1) given sin A = 3/5 and sin B= 12/13. A,B-acute angle. find a)sin(A-B) b)cos(A+B) c)tan(A-B)

2)given that tan A=3/4 180<A<360, find a)tan(A+45) b)sin(A+30)

3)given sin x= 8/17, cos= -15/17 , sin y=3/5 and cos y=4/5. Find a) sin(x-y) b)cos(x-y) c)tan(x-y)

thanks in advance.
