Question

Find mzi. 1 5 H 9 J Write your answer as an integer or as a decimal rounded to the nearest tenth.

Answer 1

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`
