According to the diagram,
AB = Adjacent Side, BC = Opposite Side, AC = Hypotenuse.
Now we need to find Sin A, Cos A, and Tan A.
Let us calculate Sin A first,
Sin A = Opposite / Hypotenuse
=> Sin A = BC / AC
=> Sin A = 15 / 17
Cos A = Adjacent / Hypotenuse
=> Cos A = AB / AC
=> Cos A = 8 / 17
Tan A = Opposite / Adjacent
=> Tan A = BC / AB
=> Tan A = 15 / 8
