Pasos de solución

9.2 cos (x) = 6.3

Multiplicar ambos lados por

10

9.2 cos (x) = 6.3

To eliminate decimal points, multiply by 10 for every digit after the decimal pointThere is one digit to the right of the decimal point, therefore multiply by

10

9.2 cos (x) \cdot 10 = 6.3 \cdot 10

Simplificar

92 cos (x) = 63

92 cos (x) = 63

Dividir ambos lados entre

92

92 cos (x) = 63

Dividir ambos lados entre

92

\frac{92 cos ( x )}{92} = \frac{63}{92}

Simplificar

cos (x) = \frac{63}{92}

cos (x) = \frac{63}{92}

Aplicar propiedades trigonométricas inversas

cos (x) = \frac{63}{92}

Soluciones generales para

cos (x) = \frac{63}{92}

cos (x) = a \Rightarrow x = arccos (a) + 2 πn, x = 2 π - arccos (a) + 2 πn

x = arccos (\frac{63}{92}) + 2 πn, x = 2 π - arccos (\frac{63}{92}) + 2 πn

x = arccos (\frac{63}{92}) + 2 πn, x = 2 π - arccos (\frac{63}{92}) + 2 πn
