Chapter 6 - 6.3 - Trigonometric Function of Any Angle - 6.3 Exercises - Page 456: 110

Part A: d = 12 miles Part B: d = 6 miles Part C: d = 6.928 miles

The sine function will be used in all parts: Part A: sin($30^{o}$) = $\frac{6}{d}$ d = 12 miles Part B: sin($90^{o}$) = $\frac{6}{d}$ d = 6 miles Part C: sin($120^{o}$) = $\frac{6}{d}$ d = 6.928 miles
