Trigonometria Plana Y Esferica De Granville Solucionario -

b / sin B = c / sin C → b = (12 * sin 74°)/sin 68°. sin 74° = 0.9613 b = (11.5356)/0.9272 ≈ 12.44.

→ 0.9250 * (-0.1736) = -0.1606

cos70° = 0.3420, cos80° = 0.1736 → product = 0.0594 sin70° = 0.9397, sin80° = 0.9848 → product = 0.9250 cos100° = -0.1736 Trigonometria plana y esferica de granville solucionario

Step 2: Law of sines. a / sin A = c / sin C → a = (12 * sin 38°)/sin 68°. b / sin B = c / sin C → b = (12 * sin 74°)/sin 68°

Spherical law of cosines for sides: cos c = cos a * cos b + sin a * sin b * cos C cos c = cos70° cos80° + sin70° sin80° cos100° Trigonometria plana y esferica de granville solucionario
