Question

cos10 + sen10 +cosx =sen50

Answer 1

Respuesta:

x = 1.97404...360° n, x=-1.97404... + 360° n

Explicación paso a paso:

cos(10°)+sin(10°)+cos(x)=sin(50°)

cos(10°)+sin(10°)+cos(x)-(cos(10°)+sin(10°))=sin(50°)-(cos(10°))

cos(x)=sin(50°)-cos(10°)-sin(10°)

x = arccos (sin(50°)-cos(10°)-sin(10°))+360°n, x = arccos (sin(50°)-cos(10°)-sin(10°))+360° n

x = 1.97404...360° n, x=-1.97404... + 360° n
