CHAPTER 11 Global Trigonometry 245 The angular length of side s is the absolute value of the di ff erence in the latitudes of points Q and R: s ¼ jLat Q À Lat Rj ¼ j þ 90: 008 À ðþ50: 008Þj ¼ 90: 008 À 50: 008 ¼ 40: 008 Now that we know r, s, and q, the spherical law of cosines tells us that: cos q ¼ cos r cos s þ sin r sin s cos q and therefore the following holds: q ¼ arccos ðcos r cos s þ sin r sin s cos qÞ ¼ arccos ðcos 102: 008 Â cos 40: 008 þ sin
