Solution:

To find cos I, applying the cosine formula below

$\cos\theta=(Adjacent)/(Hypotenuse)$

Where

$\begin{gathered} Adjacent=IJ=18\text{ units} \\ Hypotenuse=IK=22\text{ units} \\ \theta=I \end{gathered}$

Substitute the values of the variables

$\begin{gathered} \cos I=(18)/(22) \\ \cos I=0.82\text{ \lparen nearest hundredth\rparen}^(\:) \end{gathered}$

Hence, the answer is 0.82 (nearest hundredth)
