The value of 0 (zero) is always 0, regardless of the value of the trigonometric function cos(0). In this case, if cos(0) is equal to 7/9, it simply means that the cosine of the angle 0 (in radians or degrees) is 7/9, but the value of the angle itself (0) remains zero.
In trigonometry, the cosine (cos) of an angle measures the ratio of the length of the adjacent side to the hypotenuse in a right triangle. When we have cos(0) = 7/9, it means that in a right triangle with an angle of 0 degrees (or 0 radians), the length of the adjacent side is 7, and the length of the hypotenuse is 9.
Using the Pythagorean theorem, we can find the length of the opposite side:
Taking the square root of both sides:
b = √32 = 4√2
So, in this triangle, the length of the opposite side is 4√2, and the cosine of the angle 0 is indeed 7/9.

The characteristics of classical Grek architecture are options A, B, and D
Ordered columns:
There were three main different orders for formal Greek architecture. They were Doric, Ionic, and Corinthian. All of them were slightly different but showed some lineament anyway.
Elegant proportions and simple lines:
The Greeks provided some of the finest and most distinctive buildings in ancient times. Besides, some of their structures would become the main feature of some towns and cities. Greek architects focused on simplicity, proportion, perspective as well as harmony in their buildings.
Sculptures figures as decorative elements:
They placed them in predetermined areas. They had shallow reliefs and some of them were three-dimension.
