Answer 1

To find x, we need to use the pithagorean theorem:

`c^2=a^2+b^2`

In this case, we have that a = 13 m and b = 15 m, therefore:

`\begin{gathered} c^2=(13)^2+(15)^2\text{ = 169 + 225 = 394} \\ \Rightarrow c^2\text{ = 394} \end{gathered}`

Finally, we get c by applying square root on both sides of the equation to get the answer:

`\begin{gathered} c^2\text{ = 394 }\Rightarrow\text{ c = }\sqrt[]{394} \\ \end{gathered}`
