\textbf{Given:}

\mathsf{In\;\triangle\;HIJ,\;\angle{J}=90^\circ,\;HJ=13,\;IH=85,\;JI=84}

\textbf{To find:}

\mathsf{cos\angle{I}}

\textbf{Solution:}

\textsf{Here,}

\mathsf{Hypotenuse=85}

\mathsf{Adjacent\;side\;of\;\angle{I}=84}

\mathsf{Then,}

\mathsf{cos\angle{I}=\dfrac{Adjacent\;side}{Hypotenuse}}

\mathsf{cos\angle{I}=\dfrac{84}{85}}

\implies\boxed{\mathsf{cos\,I=\dfrac{84}{85}}}
