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.

Answer:
38°
Explanation:
Solve for 0 in Degrees.
B. The government banned outside trade to keep wealth in the empire.
C. Merchants and artisans made goods such as cloth and pottery.
D. Wheat, rice, and other farm crops were sold locally.
The economy of the Guptadynasty thrived as the government banned trading outside, so that the wealth is generated within the empire.
The period in which the Guptadynasty established its rule over India is regarded as the GoldenAge of the ancient India. Economicgrowth and development was at its peak during this period.
Hence, option B holds true regarding the economy of the Gupta dynasty.
