cos(x+5)= 1/2 sqrt(3),0<= x<= 2pi

Solución

cos (x + 5) = \frac{1}{2} 3, 0 \leq x \leq 2 π

Solución

x = \frac{11 π - 30}{6}, x = \frac{13 π - 30}{6}

Pasos de solución

cos (x + 5) = \frac{1}{2} 3, 0 \leq x \leq 2 π

Simplificar

\frac{1}{2} 3 : \frac{3}{2}

\frac{1}{2} 3

Multiplicar fracciones:

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

= \frac{1 \cdot 3}{2}

Multiplicar:

1 \cdot 3 = 3

= \frac{3}{2}
