## Trigonometry (10th Edition)

We can find the angle $\theta$: $\theta = 40^{\circ}-9^{\circ}$ $\theta = 31^{\circ}$ We can convert the angle $\theta$ to radians: $\theta = (31^{\circ})(\frac{\pi~rad}{180^{\circ}}) = 0.54105~radians$ We can find the distance $d$ between Pittsburgh and Panama City: $d = \theta~r$ $d = (0.54105~radians)(6400~km)$ $d = 3462.7~km$ The distance between Pittsburgh and Panama City is 3462.7 km
