What is the tangent function used to find and what are its units?

a. magnitude, kilometers (km)

b. magnitude, degrees (°)

c. direction, kilometers (km)

d. direction, degrees (°)

There is no correct answer among the choices provided above. All options are wrong because a tangent function have no units. It is defined as the ratio of the lengths between the opposite and the adjacent sides. The function is remembered as TOA which means tangent is opposite over adjacent.
