Given


\begin{gathered} IH=5 \\ IJ=9 \end{gathered}

We can find the measure of I below.

Step-by-step explanation


\begin{gathered} CosI=\frac{Adjacent\text{ }side}{Hypotenuse\text{ side}}=(IH)/(IJ)=(5)/(9) \\ I=Cos^(-1)(5)/(9) \\ I=Cos^(-1)0.98176 \\ I=56.3^(\circ\:) \end{gathered}

Answer:


I=56.3^0
