Calculation:

If we have an angle θ, then the tangent of its complementary angle (90° - θ) is equal to the cotangent of θ.

Mathematically, we can express this as:

tan(90° - θ) = cot(θ)

So, the tangent of the complementary angle is equal to the cotangent of the original angle.

∴ Option 2 is the correct answer.
