Answer 1

Find the missing side of the triangle formes using the pythagorean theorem

`\begin{gathered} a^2+b^2=c^2 \\ a^2+25^2=65^2 \\ a^2=65^2-25^2 \\ a^2=4225-625 \\ a^2=3600 \\ a=\sqrt[]{3600} \\ a=60 \end{gathered}`

add Oak road and mountain Highway together

`60+25=85`

substract airport road

`85-65=20`
