In the right triangle shown, if point A is moved to the left so that side AB is elongated, the opposite side of angle A would increase while the adjacent side would decrease. This means that:
The sine ratio, which relates the opposite side to the hypotenuse, would be affected.
The cosine ratio, which relates the adjacent side to the hypotenuse, would not be affected, since the hypotenuse remains the same.
The tangent ratio, which relates the opposite side to the adjacent side, would be affected.
Therefore, the correct option is:
C) cos A and tan A only.
