well, if o = the side opposite to the angle, h = the hypotenuse, and a = the side adjacent to the angle, sinθ = o/h cosθ = a/h tanθ = o/h

OpenStudy (unklerhaukus):

\[\boxed{\sin(\theta)=\dfrac{\text{opposite side}}{\text{hypotenuse}}}\]\[\boxed{\cos(\theta)=\dfrac{\text{adjacent side}}{\text{hypotenuse}}}\]\[\boxed{\tan(\theta)=\dfrac{\sin(\theta)}{\cos(\theta)}=\dfrac{\text{opposite side}}{\text{adjacent side}}}\]
