Question

calcule x si: cos(x+48°)=0,5

ayuda

Answer 1

Explicación paso a paso:

$\cos(x+48^{\circ})=0.5$

Aplicando el coseno inverso en ambos lados:

$\cos^{-1}(\cos(x+48^{\circ}))=\cos^{-1}(0.5)\\\\x+48^{\circ}=\cos^{-1}(0.5)\\\\x=\cos^{-1}(0.5)-48^{\circ}\\\\\boxed{x=-46.95\approx -47^{\circ}}$
