One way to determine if the function is a trigonometric identity or not is to use a calculator on the choices. Choice A does not fit. Choice B should be (sin x)^2 + (cos x)^2 to become equal to 1. Choice D> should be cot x, the inverse of tan x to become equal to cos x/ sin x. Hence, answer is C>

Answer:
x = 3
y = 6
Step-by-step explanation:
30 60 90 right triangle
Ratio of short leg : long leg : hypo = a : a√3 : 2a (a = short leg)
In this case, given long leg = 3√3
so short leg = 3
and
hypo = 2 * 3 = 6
Answer: x = 3 and y = 6
