It would be 5π6 as arctan and tan camcel out.

Explanation:

tan answers the question: what ratio is there between the opposite and the adjoining side when the angle is 5π6

arctan answers the opposite question: what angle belongs to a certain ratio of opposite and adjoining sides.

tan and arctan are opposing operators, comparable to square and square root, or multiplication and division. They cancel out each other.
