Question

a = 859 m, b = 158 m, C = 98⁰ Calcular el lado c. (teorema del coseno)​

Answer 1

Respuesta:

c = a²+b²-2ab×Cos(C)

c = ?

a = 859m

b = 158m

C = 98°

c² = (859m)²+(158m)²-2(859m)(158m)×Cos(98°) ; Cos(98°) ≈ - 0,14

c² = 737881m²+24964m²-135722m²(-0,14)

c² = 737881m²+24964m²-(-135722×0,14)m²

c² = 762845m²-(-19001,08m²)

c² = 762845m²+19001,08m²

c² = (762845+19001,08)m²

c² = 781846,08m²

√(c²) = √(781846,08m²)

c ≈ 884,221m

R// La medida del lado " c " es de cerca de 884,221m .
