tengant


The tangent of the angle at B is equal to the length of the side opposite the angle, divided by the length of the side adjacent to the angle.

Remember that the hypoteneuse side is different to the adjacent side. The hypoteneuse is the side opposite the right-angle. It is always the longest side of a right-angled triangle.

So the opposite side divided by the adjacent side is AC/AB, answer c).
