Answer 2

It's true because the common side is CB, which means both angles (<ACB and <BCD) share it, is in the middle of angle ACD, which is a right triangle as given by the information. If both angles ACB and BCD exist within <ACD and they are the only two angles that make up <ACD then they are complementary.
