(sin(75))/(101)=(sin(b))/(65)

Solución

\frac{sin ( 7 5 ^{\circ} )}{101} = \frac{sin ( b )}{65}

b = 0.67082 \dots + 36 0^{\circ} n, b = 18 0^{\circ} - 0.67082 \dots + 36 0^{\circ} n

Pasos de solución

\frac{sin ( 7 5 ^{\circ} )}{101} = \frac{sin ( b )}{65}

sin (7 5^{\circ}) = \frac{6 + 2}{4}

\frac{\frac{6 + 2}{4}}{101} = \frac{sin ( b )}{65}

Intercambiar lados

\frac{sin ( b )}{65} = \frac{\frac{6 + 2}{4}}{101}

Aplicar las propiedades de las fracciones:

\frac{\frac{b}{c}}{a} = \frac{b}{c \cdot a}

\frac{sin ( b )}{65} = \frac{6 + 2}{4 \cdot 101}

Multiplicar los numeros:

4 \cdot 101 = 404

\frac{sin ( b )}{65} = \frac{6 + 2}{404}

Multiplicar ambos lados por

65

sin (b) = \frac{65 ( 6 + 2 )}{404}

Aplicar propiedades trigonométricas inversas

b = arcsin (\frac{65 ( 6 + 2 )}{404}) + 36 0^{\circ} n, b = 18 0^{\circ} - arcsin (\frac{65 ( 6 + 2 )}{404}) + 36 0^{\circ} n
