Question 904452: Using your knowledge of trigonometric identities, ﬁnd the exact value of sin(x+y) knowing that x and y are between 0 and π/2, that sin(x)=4/5 and that sec(y)=13/5. Your answer must be a rational number, written in the form of an irreducible fraction p/q (such as 2/3, 4/5, −1/4, etc.), with q>0. Give the integers p and q.

, cos(y) = 5/13 and sin(y) = 12/13
sin(x) = 4/5, cos(x) = 3/5
sin(x+y) = sin(x)c0s(y)+ cos(x)sin(y) =
