Question

What are the steps to figuring this problem out. I have 2 out of 3 correct

Answer 1

Determine the length of missing side by using pythagoras theorem.

`\begin{gathered} (11)^2=((39)/(10))^2+x^2 \\ x^2=121-(1521)/(100) \\ =(12100-1521)/(100) \\ =(10579)/(100) \\ x=\sqrt[]{(10579)/(100)} \\ =(1)/(10)\sqrt[]{10579} \\ =(102.85)/(10) \\ \approx10.3 \end{gathered}`

So answer is,

`(1)/(10)\sqrt[]{10579}`

Or 10.3.
