no responda si no sabee. reporto!!!!!!!​

Answer 1

Respuesta:

x = 45°

Explicación:

Ecuaciones trigonometricas

[(senx + cosx)²-1] ctgx = 1

( sen²x + 2senxcosx + cos²x - 1 )ctgx = 1

( 1 + 2senxcosx - 1 )ctgx = 1

( 2senxcosx )cosx / senx = 1

2cos²x = 1

cos²x = 1/2

x = 45°

Espero te sirva , suerte :)
