Step-by-step explanation:
Remember to follow the rule: SohCahToa:
Sin (S) = Opposite/Hypotenuse
Cos (C) = Adjacent/Hypotenuse
Tan (T) = Opposite/Adjacent.
Hypotenuse is always the longest side. Adjacent is the side next to the angle, Opposite is the side opposite of the angle.
Sin(A) = (Opposite/Hypotenuse) = 8/17
Tan(A) = (Opposite/Adjacent) = 8/15
Cos(A) = (Adjacent/Hypotenuse) = 15/17
Sin(B) = (Opposite/Hypotenuse) = 15/17
Tan (B) = (Opposite/Adjacent) = 15/8
Cos (B) = (Adjacent/Hypotenuse) = 8/17
