• A. AB, BC, CA
• B. AB, CA, BC
• C. AC, AB, BC
• D. CA, BC, AB

Answer 1

The correct option is A

AB, BC, CA

In any triangle, the side opposite to the greater angle is longer.

In any triangle, the side opposite to the greater angle is longer.

The corresponding side of angle 40${}^{\circ }$ is AB.

The corresponding side of angle 75${}^{\circ }$ is AC.

The corresponding side of angle 65${}^{\circ }$ is BC.

So sides in ascending order will be AB, BC,AC
