Answer:
21/20
Explanation:
The cotangent of an angle can be calculated as the adjacent side over the opposite side.
Since IK is the adjacent side of ∠I and KJ is the opposite side of ∠I, we get that the cotangent is equal to:
[tex]\begin{gathered} \cot I=\frac{IK}{KJ} \\ \cot I=\frac{21}{20} \end{gathered}[/tex]
Therefore, the ratio that represents the cotangent of ∠I is 21/20
