Final answer:
Tan(5pi/6) and tan(5pi/3) are both equal to -sqrt(3), so they are equal.
Step-by-step explanation:
Tan is a trigonometric function that represents the ratio of the opposite side to the adjacent side of a right triangle. Tan(x) is equal to sin(x) / cos(x).
When we evaluate tan(5pi/6), we find that it is equal to -sqrt(3).
When we evaluate tan(5pi/3), we find that it is equal to -sqrt(3).
Therefore, both tan(5pi/6) and tan(5pi/3) are equal to -sqrt(3), so they are equal.
