Question

What is the length of the missing light? If Necessary round to the nearest 10th

Answer 1

Given:

The opposite side is 9.4 km.

The hypotenuse side is 9.7 km.

To find: The adjacent side b

Step-by-step explanation:

Using the Pythagoras theorem,

`\begin{gathered} \text{Hyp}^2=\text{Opp}^2+\text{Adj}^2 \\ 9.7^2=9.4^2+b^2 \\ b^2=94.09-88.36 \\ b^2=5.73 \\ b\approx2.4 \end{gathered}`

Final answer: The length of b is 2.4 km.
