RWY

Calculate the opposite direction of the runway 13.

Runways are named by a number between 01 and 36, which is generally one-tenth of the azimuth of the runway's heading in degrees: a runway numbered 09 points east (90°), runway 18 is south (180°), runway 27 points west (270°) and runway 36 to the north (360° rather than 0°).

A runway can normally be used in both directions and is named for each direction separately.

Final Answer:

x =  31

Step-by-step explanation:

$$\begin{gathered} x=\frac{(130^{\circ }+180^{\circ })\mathrm{m}\mathrm{o}\mathrm{d}360^{\circ }}{10}=\frac{310^{\circ }\mathrm{m}\mathrm{o}\mathrm{d}360^{\circ }}{10} \\ x=31 \end{gathered}$$
