First, you need to figure out whether you need to use sin, cosine or tan.
Since we know that we need to find the adjacent side of the triangle and also since we already know the opposite side of the triangle from the angle, we can use tan.
tan(20)=opposite/adjacent
tan(20)=(146.5)/adjacent
adjacent=(146.5)/tan(20)
